Normal Vital SignsIn most medical settings, the four standard primary vital signs are as follows: [1]
Heart rate (pulse) Respiratory rate Blood pressure Body temperature
Normal values for each of these vital signs vary by age and, in some cases, by sex.

Temperature
The average normal core temperature is generally considered to be between 98.0°F (36.6°C) and 98.6°F (37°C) when measured orally and about 1°F higher when measured rectally.[2]
Retraksi interkosta
- retraksi interkostal (meningkatnya pemakaian otot-otot leher dan dada sebagai usaha untuk bernafas).
BronkiolitisGEJALAGejalanya berupa:- batuk- wheezing (bunyi nafas mengi)- sesak nafas atau gangguan pernafasan- sianosis (warna kulit kebiruan karena kekurangan oksigen)- takipneu (pernafasan yang cepat)- retraksi interkostal (otot di sela iga tertarik ke dalam karena bayi berusaha keras untuk bernafas)- pernafasan cuping hidung (cuping hidung kembang kempis)- demam (pada bayi yang lebih muda, demam lebih jarang terjadi).
Krup (Laringotrakeobronkitis)
Gejala lainnya yang mungkin ditemukan:- stridor (bunyi pernafasan yang bernada tinggi)- sianosis (warna kulit menjadi kebiruan karena kekurangan oksigen)- retraksi interkostal (meningkatnya pemakaian otot-otot leher dan dada sebagai usaha untuk bernafas).
DIAGNOSADiagnosis ditegakkan berdasarkan gejala dan hasil pemeriksaan fisik yang menunjukkan adanya retraksi interkostal pada saat anak menghirup nafas.Pemeriksaan dengan stetoskop menunjukkan adanya wheezing (bunyi nafas mengi), fase inspirasi (penghirupan udara) dan ekspirasi (penghembusan udara) yang memanjang dan berkurangnya suara pernafasan.Rontgen leher bisa menunjukkan adanya penyempitan trakea.
7. Retraksi intercostal terlihat pada saat penarikan intercosta secara paksa sehingga costa tertarik keatas.
Diagnosis etiologik berdasarkan pemeriksaan mikrobiologis dan/atau serologismerupakan dasar terapi yang optimal. Akan tetapi, penemuan bakteri penyebab tidak selalu mudah karena memerlukan laboratorium penunjang yang memadai. Tidak ada gejala distress pernafasan, takipneu, batuk, ronki, dan peningkatan suara pernafasan dapat menyingkirkan dugaan pneumonia. Terdapatnya retraksi epigastrik, interkostal, dan suprasternal merupakan indikasi tingkat keparahan.

1. Retraksi interkosta : kemungkinan retraksi pada obstruksi jalan nafas2. Retraksi Intercostal pada saat inspirasi
Menunjukkan adanya obstruksi jalan nafas atau menurunnya complence paru-paru yang menyebabkan paru-paru kolaps.
VOCAL FREMITUS
Palpasi thorax
Tactil fremitus : kedua telapak tangan pemeriksa menempel pada dinding thorax : seperti
pada bagian posterior atau punggung, kemudian pasien disuruh berucap kata-kata seperti 77
dengan nada yang sedang kemudian secara simetris, dibandingkan getaran yang timbul pada
dinding thorax yang dirasakan pada kedua telapak tangan pemeriksa.
- Fremitus meningkat bisa pada :
- Infiltrat paru
- Compressive atelektasis
- Cavitas paru
Fremitus taktil memberikan informasi yang berguna mengenai kepadatan jaringan paru-paru dan rongga dada dibawahnya.Fremitus meningkat pada keadaan dengan infiltrat paru, compressive atelektasis, cavitas paru. Keadaan seperti ini kepadatan paru-paru meningkat seperti konsolidasi, sehingga meningkatkan penghantaran fremitus taktil.Fremitus menurun atau melemah pada keadaan penebalan pleura, efusi pleura, pneumotoraks, emfisema paru dan obstruksi dari bronkus. Keadaan klinis yang mengurangi penghantaran
gelombang suara ini akan mengurangi fremitus taktil. Jika ada jaringan lemak yang berlebihan di dada, udara atau cairan di dalam rongga dada, atau paru-paru yang mengembang secara berlebihan, fremitus taktil akan melemah.
Fremitus vokal menurun pada saluran udara bagian atas dapat menunjukkan
• Para obstruksi bronkus utama dari
• Pneumo-, hidro-, haemothorax
• Emfisema paru-paru
• adipositas juga dapat menjadi penyebab penurunan fremitus vokal.
Suara fremitus meningkat
• Pada pneumonia
• Dalam Abses
• Dalam ateletasis
• Dalam gua
Tidak adanya fremitus biasanya menunjukkan obstruksi bronkus besar dari, yang mungkin terjadi sebagai hasil dari
aspirasi benda asing. Penurunan atau fremitus absen adalah selalu dicatat dan dilaporkan untuk penyelidikan lebih
lanjut. Selama palpasi getaran lain yang menunjukkan kondisi patologis dicatat. Salah satunya adalah friction rub
pleura, yang memiliki sensasi okulasi. Hal ini sinkron dengan gerakan pernapasan dan merupakan hasil menentang
permukaan lapisan pleura yang meradang bergesekan satu sama lain.
Kertak dirasakan sebagai sensasi, kasar retak sebagai menekan menyerahkan daerah yang terkena. Ini adalah hasil
dari keluarnya udara dari paru-paru ke dalam jaringan subkutan dari cedera atau intervensi bedah. Kedua
menggosok gesekan pleura dan kertak biasanya dapat didengar serta dirasakan.
PALPASI
1. Menurunnya atau hilangnya Vocal Fremitus
Vokal fremitus terjadi karena transmisi getaran melalui bronchotracheal melalui septum paru dan pleura. Gangguan transmisi karena misalnya destroyed lung, penebalan pleura, atau efusi akan menurunkan vocal fremitus. Sumbatan jalan nafas atas akan menghilangkan vocal fremitus.
2. Meningkatnya vocal fremitus
Peningkatan tekanan di septum paru akan meningkatkan transmisi getaran. Terjadi pada pneumonia.

RONKI BASAH HALUS
1. Ronki basah. Ronki basah sering juga disebut dengan suara krekels (crackles) atau rales. Ronki basah merupakan suara berisik dan terputus akibat aliran udara yang melewati cairan. Ronki basah halus, sedang atau kasar tergantung pada besarnya bronkus yang terkena dan umumnya terdengar pada inspirasi. Ronki basah halus biasanya terdapat pada bronkiale, sedangkan yang lebih halus lagi berasal dari alveolus yang sering disebut krepitasi, akibat terbukanya alveoli pada akhir inspirasi. Sifat ronki basah ini dapat nyaring (infiltrat)atau tidak nyaring (pada edema paru). Krekel dapat dihilangkan dengan batuk, tapi mungkin juga tidak. Krekels mencerminkan inflamasi atau kongesti yang mendasarinya dan sering timbul pada kondisi seperti pneumonia,bronkitis, gagal jantung kongesti, bronkiektasis, dan fibrosis pulmonal serta khas pada pneumonia dan interstitial atau fibrosis.Timing (waktu) ronkhi ini sangat penting. Ronki inspirasi awal menunjukan kemungkinan penyakit pada jalan napas kecil, dan khas untuk hambatan jalan napas kronis. Ronki lainnya terdengar pada inspirasi awal dan bersifat kasar sedang. Ronki berbeda dengan yang terdengar pada gagal ventrikel kiri yang terjadi di akhir siklus pernapasan.Ronki pada inspirasi akhir atau paninspirasi menunjukan kemungkinan penyakit yang mengenai alveoli dan dapat bersifat halus, sedang, atau kasar. Ronki halus dideskripsikan sebagai bunyi rambut yang digosok-gosok dengan jari-jari tangan. Bunyi ini secara khas disebabkan oleh fibrosis paru. Ronki sedang biasanya akibat gagal ventrikel kiri, bila ada cairan alveoli merusak fungsi dari surfaktan yang disekresi dalam keadaan normal. Ronki kasar khas untuk pengumpulan sekret yang tertahan dan memiliki kualitas seperti mendeguk yang tidak mengenakan. Bunyi ini cenderung berubah dengan batuk yang juga memiliki kualitas yang sama. Bronkiektasis paling sering menyebabkan terjadinya ronki, tetapi setiap penyakit yang menimbulkan retensi sekret dapat menyebabkan gangguan ini.
Ronki mungkin disebabkan oleh hilangnya stabilitas jalan napas perifer yang kolaps pada saat ekspirasi. Tekanan inspirasi yang tinggi menyebabkan terjadinya pemasukan udara cepat ke dalam unit-unit udara distal. Hal ini menyebabkan pembukaan yang cepat dari alveoli dan bronkus kecil
atau bronkus sedang yang mengandung sekret pada bagian-bagian paru yang berdeflasi sampai volume residu. 3
Ronki basah (cracklesatau rales)merupakan suara napas yang terputus-putus, bersifat nonmusical, biasanya terdengar saat inspirasi akibat udara yang melewati cairan dalam salurannapas. Ronki basah dibagi ronki basah halus dan kasar tergantung besarnya bronkus yangterkena. Ronki basah halus terjadi karena adanya cairan alveoli pada bronkiolus, sedangkan padaronki basah yang lebih halus berasal dari alveoli (krepitasi)akibat terbukanya alveoli pada akhirinspirasi terjadi terutama pada fibrosis paru. Sifat ronki basah ini dapat bersifat nyaring (bila adainfiltrasi misal pneumonia) atau tidak nyaring (edema paru). (Rumende, 2007)AdapunPatomekanisme ronchi basah yaitu : Jika tekanan hidrostatik anyaman kapiler paru-paru meningkat melebihi tekanan onkotik pembuluh darah maka akan terjadi transudasi cairan ke dalam interstisial. Apabila kecepatannyamelebihi kecepatan drainase limfatik maka akan timbul edema interstisial. Bila terjadi peningkatan tekanan lebih lanjut, cairan akan merembes ke alveoli sehingga menimbulkanedema paru.Seperti klarifikasi “ronchi basah” yaitu bunyi yang terdengar bila terdapat cairan di dalam bronkus atau alveoli. Ronchi terdengar di basal medial paru karena cairan terakumulasi di bagian bawah paru karena pengaruh gaya gravitasi
KREPITASi
KrepitasiKrepitasi (ronki) adalah bunyi singkat, tidak kontinue, tidak musikal, banyak didengar
selama inspirasi. Bunyi krepitasi seperti bunyi yang dibuat dengan menggosokkan rambut di dekat telinga atau bunyi ketika memasukkan garam ke dalam api. Krepitasi ditemukan pada edema paru-paru, gagal jantung kongestif dan fibrosis paru.
Ronchi basah (krepitasi) : bunyi tambahan yang terdengar tidak kontinyu pada waktu inspirasi seperti bunyi ranting kering yang terbakar, disebabkan oleh secret di dalam alveoli atau bronkiolus. Ronki basah dapat halus, sedang, dan kasar. Ronki halus dan sedang dapat disebabkan cairan di alveoli misalnya pada pneumonia dan edema paru, sedangkan ronki kasar misalnya pada bronkiekstatis.

alveolar infiltrateOpacification of air spaces, caused by the filling of alveoli with blood, pus, or fluid. Alveolar infiltrates are seen on the chestradiograph as patchy areas of increased density, often surrounding air bronchograms.

Available in high-resolution and several sizes to fit the needs of your project.
Infiltrate is when your alveolar spaces are filled with some sort of fluid, i.e. transudate, exudate.
Consolidation refers to the lung becoming a hard, firm mass, which is very characteristic of lobar pneumonia. So this can be due to an exudative infiltrate, for example, in lobar pneumonia, where the cell debris and pus is literally filling up the spaces and instead of giving your lungs this squishiness that you see on autopsy it makes it hard and less pliable, and less able to fill up with air.
So consolidation = texture, infiltration = filling up of the lungs. You can have consolidation with or without infiltration.
The term "pulmonary infiltrate" is considered a context dependent, nonspecific and imprecise descriptive term when used in radiology reports (plain film or CT).
From a pathophysiological perpestive, the term "infiltrate" refers to “an abnormal substance that accumulates gradually within cells or body tissues” or “any substance or type of cell that occurs within or spreads as through the interstices (interstitium and/or alveoli) of the lung, that is foreign to the lung, or that accumulates in greater than normal quantity within it”
While when used with a better anatomic reference, such as alveolar, air space, interstitial, or nodular, it may occasionally be helpful in suggesting an underlying pathologic basis for the findings on the radiograph, the use of the term in general is discouraged.
According to a study by Patterson et.al, the use of the term "infiltrate" on its own was not shown to be very meaningful for the clinician or very beneficial to the patient 1.
According the Fleischer Thoracic Society recommendations, use of the term "infiltrate" remains controversial and is no longer recommended 3.
Interstitial vs Alveolar Lung Patternsunder construction
IntroductionThis page considers all aspects of the appearances of interstitial and alveolar opacity demonstrated on chest plain film imaging. Radiographers who are able to differentiate alveolar from interstitial lung patterns are operating at a very high level and will find a whole new appreciation of chest radiography. An appreciation of the features of these patterns will prevent you from describing appearances as cloudy, fuzzy etc. You are more likely to gain the respect of your fellow health professionals and impart meaningful information if you can describe an appearance using correct descriptors- e.g "there is widespread coarse interstitial opacity" rather than "the lungs look a bit fuzzy".
CautionThis is not easy- in fact, this is the difficult end of plain film image interpretation. The interpretation difficulties are as follows
The appearances can be subtle Interstitial patterns can be mixed (linear, reticular, or nodular) There can be mixed alveolar and interstitial patterns There can be other patterns present (tumour, pleural effusion, atelectasis etc) There can be acute on chronic changes. The causes of interstitial lung opacity are numerous
Interstitial Opacity on CXR- anatomy, causes and appearances.The interstitium of the lung consists of the supporting structures such as pulmonary vessels, bronchi, and connective tissue. On the normal CXR, the visible interstitium consists primarily of the pulmonary vessels, which are most pronounced at the hila, and decrease in
prominence towards the periphery (in fact, under normal circumstances, the pulmonary vessels are not visible in the periphery on a CXR because they are too small to resolve at this point). Most lung diseases cause an increase in the radiodensity of the lung, and if this is due to a relative thickening of the interstitium- this will be manifest as increased prominance of the interstitial markings on the CXR. If generalized or diffuse, this will likely appear as a linear or reticular pattern, whereas if localized, it may appear as multiple tiny nodules.
Note that in diseases confined to the interstitium (i.e. sparing the alveoli) the lung will still appear aerated—the basic appearance is of an aerated lung that has too many “markings.” Common causes of this pattern include pulmonary edema, inflammation, fibrosis, and tumour.
The interstitium surrounds bronchi, vessels, and groups of alveoli. When there is disease in the interstitium it manifests itself by reticulonodular shadowing (criss cross lines or tiny nodules or both). The main two processes affecting the interstitium are accumulation of fluid (occurring in pulmonary oedema or in lymphangitis carcinomatosa) and inflammation leading to fibrosis (occurring in industrial lung disease, inflammatory arthritides such as rheumatoid arthritis, inflammation of unknown cause such as cryptogenic fibrosing alveolitis and sarcoidosis).

Causes of Interstitial lung opacity
- Common identifiable causes:
a) infectious causes, e.g.: non-tuberculous mycobacteria & certain fungal infections
b) occupational causes, e.g.: asbestos & silica
c) drug reactions, e.g.: methotrexate & amiodarone
d) neoplastic causes, e.g.: metastatic cancer, bronchoalveolar cell carcinoma (a form of lung cancer)
Causes of Alveolar Opacity pneumonitis pulmonary contusion pulmonary oedema Aspiration
The Meaning of the Term 'Consolidation'
One of the unfortunate aspects of the term consolidation is that its meaning can be different depending on who is using the term. When a clinician uses the term consolidation, he/she is usually referring to a consolidation associated with acute pneumonia. Thus, the term consolidation and pneumonia have very similar meaning and are almost used interchangeably. Strictly speaking, the term consolidation does not imply any particular aetiology or pathology. Acute pneumonia is the commonest cause but not the only cause of consolidation. (other causes include chronic pneumonia, pulmonary oedema and neoplasm). Thus when a radiologist has reported a chest X-ray examination and notes the presence of consolidation he/she is simply stating that some of the lung airspace has been replaced by a fluid. Sutton, Textbook of Radiology, 2nd ed.,1975,
This is a basic video that explains consolidation in simple terms
Notes Consolidation may be complete or incomplete The distribution of the consolidation can vary widely. A consolidation could be described as “patchy”, “homogenous”, or generalised”. A consolidation may be described as focal or by the lobe or segment of lobe affected
Sutton, Textbook of Radiology, 2nd ed.,1975, p325
Interstitial vs Alveolar PatternsRecognition of a plain film interstitial pattern is important because it identifies the abnormal density as being within the supporting tissues of the lung rather than within the air spaces, pleural space, mediastinum, or outside the thoracic cavity- it indicates the infiltrate's cellular rather than fluid nature.
Alveolar Opacity Interstitial Opacity
Alveolar Opacity- Definition
Alveolar opacity refers to opacity on chest X-ray associated with fluid filling of the airspaces.
Interstitial Opacity- Definition
The interstitium refers to the supporting structures of the lung. An interstitial opacity on chest X-ray refers to an abnormal appearance of the lung interstitium
Well demonstrated normal interlobular septa in patient with pneumothorax
(pneumothorax causes alveolar compression and so, the intersitium forms a larger component of the lung volume).
Alveolar Opacity- Plain Film Pattern Interstitial Opacity- Plain Film Pattern
Opacity is often described as fluffy, cotton wool-like, or cloud-like
Interstitial opacity can be linear, reticular, nodular or reticulonodular.
Alveolar Lung Patterns on CXR
Alveolar pattern results from flooding of the end air spaces (acini) with fluid (pus, blood, edema) only rarely with cellular material. As individual acini become filled the fluid spreads to adjacent ones through the interalveolar pores. This results in the typical
radiographic pattern of a poorly margined ("fluffy") density. The densities may spread and their borders coalesce. This may progress until all acini within a lung lobe are filled. There may be a sharp border at the edge of a lung lobe due to the pleura blocking further spread of the fluid into the adjacent lung lobe. As the number of fluid filled adjacent acini increases, the air filled, large and medium sized bronchi become evident as linear radiolucent branching structures (air bronchogram). The air-filled bronchi are surrounded by a fluid density and the bronchial wall and adjacent vessel are not seen. When a bronchus branches perpendicular to the x-ray beam it will be seen as a round radiolucent dot.Radiographic Diagnosis of Pulmonary DiseaseNorman Ackerman, DVM, DACVR
This patient aspirated IV contrast medium. The post-contrast image was taken within a few minutes of aspiration. The dense contrast media has filled the alveoli as well as coating some of the larger airways. The whispy/fluffy/cloudy pattern is characteristic of alveolar airspace filling.
Interstitial Lung Patterns on CXR
Pracical Approach to Interstitial Lung Diseases, A. Nour-Eldin
There are 4 basic interstitial lung patterns
1. linear- septal lines (Kerley lines)
2. reticular- mesh like appearance, lines in all directions
This is a nodular pattern in a patient with lymphangitis
carcinomatosis.
Reticulonodular pattern in a patient with COPD
The linear pattern on chest radiography consists of thin linear opacities which are either 2 to 6 cm long within the lungs oriented radially toward the hila or 1 to 2 cm long at right angles to, and in contact with, the lateral pleural surfaces. These linear opacities have been referred to as Kerley A and Kerley B lines, respectively, although the descriptors “septal thickening” or “septal lines” are now preferred for the latter.
Histologically, this linear pattern represents thickening of either the bronchovascular/axial
The reticular pattern as seen on chest radiography and computed tomography (CT or HRCT) is depicted by numerous, small,
The nodular pattern on chest radiography is characterized by multiple small, discrete, rounded opacities that range in diameter from 2 to 10 mm.The differential diagnosis for the nodular pattern can be separated into 3 main categories based on etiology: nodular metastases, nodular pneumoconioses and the granulomatous diseases. The most common malignancies resulting in this pattern are thyroid, breast and renal-cell carcinoma, with the nodules measuring up to 10 mm in diameter.
interstitium (Kerley A) or the peripheral interstitium (Kerley B).The linear opacities may be single or multiple, regional or diffuse, and short or long, depending on the etiology and severity of disease.
The most common cause of the linear pattern is hydrostatic pulmonary edema, but other etiologies include lymphangitic carcinomatosis, and atypical interstitial pneumonias such as those caused bymycoplasma, chlamydia, cytomegalovirus (CMV), and respiratory syncytial virus (RSV). Interstitial pulmonary edema tends to be symmetric in distribution while atypical infections and lymphangitic carcinomatosis may be asymmetrical.

Note the obscuration of the normal lung markings in the patient with the linear interstitial pattern
2. Reticular
A reticular pattern results from the summation or superimposition of irregular linear opacities. The term reticular is defined as meshed, or in the form of a network. Reticular opacities can be described as fine, medium, or coarse, as the width of the opacities increases. A classic reticular pattern is seen with pulmonary fibrosis, in which multiple curvilinear opacities form small cystic spaces along the pleural margins and lung bases (honeycomb lung)
3. Nodular
Source: Chest Radiology, Pretest USMLE, Part 2, Juzar Ali and Warren R. Summer
A nodular pattern consists of �multiple round opacities, generally ranging in diameter from 1 mm to 1 cm
Nodular opacities may be described� as miliary (1 to 2 mm, the size of millet seeds), small, medium, or large, as the diameter of the opacities increases
A nodular pattern, especially with �predominant distribution, suggests a specific differential diagnosis
This x-ray shows a bilateral diffuse miliary nodular pattern involving both lung fields with no loss of volume.
4. Reticulonodular
This patient has a primary lung cancer with lymphatic spread (lymphangitic carcinomatosis). The lower zone of the left lung shows a coarse reticulonodular pattern.
Compare the appearance of the lower zone of the left lung with an earlier CXR on the same patient (below)
A reticulonodular pattern results from a combination of reticular and nodular opacities.A reticulonodular pattern is often difficult to distinguish from a purely reticular or nodular pattern, and in such a case a differential diagnosis should be developed based on the predomi
nant pattern. If there is no predominant pattern, causes of both nodular and reticular patterns should be considered.

A recent chest X-ray showed that I have hyperinflated lungs. What could cause this?Answers from Edward C. Rosenow III, M.D.
Hyperinflated lungs can be caused by obstructions in the passages that deliver air to your lung tissue. Air gets trapped within the lung and causes it to overinflate. Hyperinflation can also occur when the air sacs in your lungs become less elastic, which interferes with the expulsion of air from your lungs.
One of the most common causes of hyperinflated lungs is chronic obstructive pulmonary disease (COPD) — a disorder that includes emphysema. Certain lung problems, such as asthma and cystic fibrosis, also can cause hyperinflation.
In some cases, lungs may appear hyperinflated on X-rays for reasons unrelated to lung function. If you aren't experiencing shortness of breath, there's probably nothing to worry about. However, if it isn't clear what is causing the hyperinflation, your doctor may recommend additional testing.
Hyperinflated lungsCase contributed by Dr Ian Bickle
Chest xrays demonstrates very marked hyperinflation of both lungs. Over 11 posterior ribs are seen, the diaphragms are flattened and there is enlargement of the retrosternal airspace. Pulmonary vasculature not terribly distorted, although there is some prominence of the pulmonary arteries.
3 study questions availableAnnotated images (different patient)
The normal dome of each hemidiaphragm should rise at least 1.5cm above a line connecting the costophrenic angle posteriorly and sternophrenic angle anteriorly.
Lateral chest x-ray from a different (normal but well inflated) patient.
The thickness of the space between the ascending aorta and the sternum is normally no more than 2.5cm.
The normal dome of each hemidiaphragm should rise at least 1.5cm above a line connecting the costophrenic angle posteriorly and sternophrenic angle anteriorlyCase Discussion:
This case demonstrates unequivocal and marked hyperinflation secondary to emphysema.

Overview
There are 3 major patterns of pulmonary opacity:
1. Airspace filling
Localized = segmental Diffuse or multifocal
2. Interstitial patterns
Reticular—fine or coarse linear shadows Reticulonodular
e. Cor / Jantung (bentuk dan ukuran) --> dengan menggunakan CTR (Cardiothoraco ratio). normalnya pada orang dewasa adalah 48%-50%, sedangkan pada anak-anak sebesar 52%-53%. Cara menghitungnya adalah a + b : c
f. Mediastinumg. Corakan BronkovaskulerUntuk corakan bronkovaskuler, normalnya hanya terdapat pada 1/3 lapangan paru dari central pada dewasa, sedangkan pada anak hanya 1/4 dari lapangan paru. Corakan bronkovaskuler yang meningkat dapat menjadi suatu tanda suatu proses perandangan paru misalnya pada bronkitis. h. Lesi Parenkim Paruerdapat banyak gambaran lesi yang mungkin terjadi. Misal pada Tuberkulosis (TB) bisa terdapat gambaran infiltrat, fibrotik, kavitas, dan lain-lain. Proses TB aktif ditandai dengan adanya lesi kavitas atau infiltat. Sementara bekas TB lama atau yang sudah tidak aktif lagi bisa tampak gambaran fibrotik berupa garis-garis radioopaque dengan batas yang tegas. Bisa juga tampak gambaran metastasis pada parenkim paru dengan adanya bentukan-bentukan lesi yang noduler, milier, koin, cannon ball, dll

Kemudian nilai juga parenkim paru, keadaan hilus, corakan bronkovaskuler, dan apakah terdapat lesi atau
tidak. Hilus merupakan tempat keluar masuknya arteri dan vena pulmonalis, bronkus, dan juga saluran limfe.
Normalnya diameter hilus sama dengan diameter trakea. Pada foto rontgen, hilus memberikan gambaran
yang padat. Untuk corakan bronkovaskuler, normalnya hanya terdapat pada 1/3 lapangan paru dari central
pada dewasa, sedangkan pada anak hanya 1/4 dari lapangan paru. Corakan bronkovaskuler yang meningkat
dapat menjadi suatu tanda suatu proses perandangan paru misalnya pada bronkitis, pneumonia, dll.
Kemudian lesi pada parenkim paru. Terdapat banyak gambaran lesi yang mungkin terjadi. Misal pada
Tuberkulosis (TB) bisa terdapat gambaran infiltrat, fibrotik, kavitas, dan lain-lain. Proses TB aktif ditandai
dengan adanya lesi kavitas atau infiltat. Sementara bekas TB lama atau yang sudah tidak aktif lagi bisa
