As high as these numbers are, thextent of the problem is actually much greater, as offi-ially reported cases grossly understate the true incidencef abuse [2,3].

In some children, physical examination and historyay clearly indicate that physical abuse has occurred.

n other children, however, the diagnosis of physicalbuse is not so straightforward. It requires consider-tion of possible underlying metabolic and geneticonditions [4-8] and usually relies on the findings of aultidisciplinary team that includes physicians, socialorkers, and legal authorities. Imaging often plays aajor role in the detection and documentation of

Child abuse injuries can involve any site in the humanody. Physically abused children may present with hol-

ow viscus and solid organ injuries, superficial and deepoft tissue injuries, thermal injuries, or fractures [10].ractures occur in up to 55% of child abuse victims [11].ractures most often involve the long bones with lesser

nvolvement of the skull, ribs, clavicles, pelvis, and other

Fractures that are highly specific for nonaccidentaltrauma in normal children include those involving theribs, metaphyseal-epiphyseal injuries, and avulsivefractures of the clavicle and acromion process [13].Highly suggestive skeletal injuries include fracturesthat are unsuspected or inconsistent with the providedhistory or age of the child, multiple fractures involvingmore than one skeletal area, fractures of differing ages,and a combination of skeletal and nonskeletal injuries[13]. In addition, fractures of the radius, ulna, tibia,fibula, or femur that occur in children aged � 1 yearand midshaft or metaphyseal humeral fractures shouldbe considered suspicious for abuse [14]. A recent sys-tematic review of the literature on fractures and childabuse found the child’s motor developmental level tobe a key discriminator for abuse in certain fractures[15]. In particular, femoral fractures in a child who isnot yet walking and unexplained humeral fractures inchildren aged � 15 months should be considered sus-picious for abuse. This review also found that multiplerib fractures in any location without overt trauma werestrongly associated with abusive injury but that theposterior location of a rib fracture was not a discrimi-nator for abuse [15].

Radiographic Skeletal Survey

The radiographic skeletal survey is the primary imagingexamination for detecting fractures [12,16-19]. Com-pared with bone scintigraphy, the radiographic skeletalsurvey is more sensitive for detecting skull and metaph-yseal long-bone fractures [20]. The skeletal survey shoulde composed of frontal and lateral views of the skull,

ateral views of the cervical spine (if not included on theateral skull view) and thoracolumbosacral spine, andingle frontal views of the long bones, chest, and abdo-en. Oblique views of the ribs should be obtained to

The images should be obtained using high-detailmaging systems and coned to the specific area of interestor each of the body parts with separate views of eachrm, forearm, thigh, leg, hand, and foot to improve im-ge quality and diagnostic accuracy [19,24-26] (see Ap-endix).The recommendations for use of skeletal surveys

ractures are performed in children aged � 1 year12,27], and 80% of children with fractures due tohild abuse are aged � 18 months [10,15]. Radio-raphic skeletal survey is recommended in all childrenged � 2 years in whom there is suspicion of abuseVariant 1). In children aged 2 to 5 years, performancef skeletal survey should be based on the presence ofther clinical findings and the need to document theresence or absence of injuries. In this older group ofhildren, however, skeletal imaging should be stronglyonsidered in a child who has unexplained craniocere-ral or abdominal injuries or fractures that are suspi-ious for abuse. In addition, a repeat skeletal surveyerformed approximately 2 weeks after the initial ex-mination can provide additional information on theresence and age of child abuse fractures [25,26] andshould be performed when abnormal or equivocalndings are found on the initial study and when abuse

Bone Scintigraphy

Bone scintigraphy is a complementary examinationfor detecting bone injuries [11,20,28]. It should beused when the radiographic skeletal survey is negativebut clinical suspicion remains high and a search forfurther evidence of skeletal trauma is still necessary.To increase sensitivity, the bone scan should includethe use of pinhole collimators and differential countsof the metaphyses. A bone scan is especially good fordetecting periosteal trauma and rib, spine, pelvic, andacromion fractures [28].

ead Trauma

lthough less frequent than skeletal injuries, mosthild abuse fatalities are the result of head trauma [7],

and head injury due to child abuse is the principalcause of death in children aged � 2 years [29]. Sub-

ural hematoma is the most commonly seen intracra-ial abnormality [30]. Additional craniocerebral inju-ies include cerebral contusion, epidural hematoma,erebral edema, subarachnoid hemorrhage, and uni-ateral hypoxic-ischemic injury [30-34].

Imaging the head in children with suspected abuseepends on the child’s age and type of presentationVariant 2). In children with skull fractures or clinicaligns and symptoms of intracranial injury, an imme-iate noncontrast CT scan of the head should be per-ormed (Variants 3 and 4). If the CT scan does notetect significant lesions that require rapid neurosur-ical intervention and the clinical presentation war-ants further assessment, an MRI scan of the headhould be performed. The MRI study should include1-weighted and T2-weighted sequences with protonensity or inversion recovery and gradient-echo se-uences. In addition, diffusion-weighted sequencesre suggested to indicate whether acute cerebral injurys present [19]. In a child with abnormal CT findings,dditional assessment with MRI should be consideredo further assess the extent of posttraumatic injury.

of head injury [18,29,33]. Physical examination, in par-icular the absence of retinal hemorrhages, should not besed to determine the need for imaging, as intracranial

njury may occur in the absence of retinal hemorrhages29,33]. Skull radiographs are also unreliable. Althoughkull radiographs may detect fractures associated withntracranial pathology [37], they do not provide ade-

quate screening, since significant traumatic intracranialpathology may occur in the absence of skull fractures[33,38,39].

In one study [29], 37% of children aged � 2 yearswith “high-risk” criteria (defined as rib fractures, mul-tiple fractures, facial injuries, or age � 6 months) and

ithout overt signs of head injury who underwentead CT or MRI had occult head injuries. In thistudy, 18 of the 19 children with occult head injuriesere aged � 1 year. Another study [33] of 51 children

ged � 4 years with no signs of intracranial injury whonderwent skeletal survey for abuse found that 29% ofhildren who underwent neurologic imaging had evi-ence of intracranial injury that included subduralematoma, epidural hematoma, or cerebral edema.iven these studies, clinicians should have a relatively

ow threshold for performing either CT or MRI of theead in children with suspected abuse. Magnetic res-nance imaging avoids the radiation of CT and is aarticularly good choice in the nonemergent setting tomage these “high-risk” children without overt neuro-ogic signs or symptoms.

hest are rare but may include hemopericardium, car-iac contusions, and lacerations, pleural effusion, lungontusions, and chylothorax [7,40,41]. Nonskeletalnjuries to the abdomen and pelvis include pan-reatitis, pancreatic pseudocysts, and lacerations andontusions of the liver, adrenal gland, spleen, andidneys, as well as injury and rupture of the bladdernd bowel [40,42]. Victims of nonaccidental abdom-nal trauma tend to be younger and have a more de-ayed presentation than those who experience acciden-al trauma [43]. The delay in presentation may beelated to the caretaker’s delay in bringing the patiento medical attention, inconsistent history, or theagueness of symptoms that may accompany thenjuries. In addition, independent of concomitant in-ury, blunt trauma due to child abuse “is associatedith a 6-fold increased odds of death compared to

hildren whose injuries resulted from other mecha-isms” [44].In most cases, imaging for assessing these injuries

Theeed for oral contrast is at the discretion of theadiologist, and its use should be strongly consideredhen there is concern for duodenal hematoma. Paren-

SUMMARY

● The appropriate imaging of pediatric patients beingevaluated for suspected physical abuse depends on theage of the child, the presence of neurologic signs andsymptoms, evidence of thoracic or abdominopelvicinjuries, and whether the child’s injuries are discrepantwith the clinical history.

● An x-ray skeletal survey is always indicated in a childaged � 24 months. In older children, a skeletal surveycan be performed, but it is often more appropriate totailor the radiographs to the areas of suspected injury.

● A CT scan of the head without contrast is always indi-cated in a patient with seizures or neurologic signs andsymptoms and when there is a history of head trauma.

● A CT scan of the head should be strongly considered in“high-risk” children (rib fractures, multiple fractures,facial injuries, or age � 6 months) and children withthoracic or abdominopelvic injuries and discrepantclinical histories.

● MRI of the head may be needed for further assessmentafter head CT and may be useful whether head CTresults are positive or negative. When the child issymptomatic, however, head CT should not be de-layed if MRI is to be obtained.

● A whole-body 99mTc bone scan may be helpful if thex-ray skeletal survey is negative and high clinical sus-picion remains.

● CT scans of the chest, abdomen, or pelvis are indicatedif there are signs and symptoms of abuse or if abnormalfindings are seen on conventional radiography, partic-ularly when there is a discrepancy with clinical history.

● A CT scan of the abdomen and pelvis should always beperformed with intravenous contrast unless the patienthas an absolute contraindication to it.

ANTICIPATED EXCEPTIONS

Nephrogenic systemic fibrosis is a disorder with a sclero-derma-like presentation and a spectrum of manifesta-tions that can range from limited clinical sequelae tofatality. It seems to be related to both underlying severerenal dysfunction and the administration of gadolinium-based contrast agents. It has occurred primarily in pa-tients on dialysis, rarely in patients with very limitedglomerular filtration rates (ie, �30 mL/min/1.73 m2),nd almost never in other patients. There is growingiterature regarding nephrogenic systemic fibrosis. Al-hough some controversy and lack of clarity remain, theres a consensus that it is advisable to avoid all gadolinium-ased contrast agents in dialysis-dependent patients unlesshe possible benefits clearly outweigh the risk and to limithe type and amount in patients with estimated glomerularltration rates � 30 mL/min/1.73 m2. For more informa-

ion, please see the ACR’s Manual on Contrast Media [45].

ELATIVE RADIATION LEVELNFORMATION

otential adverse health effects associated with radiationxposure are an important factor to consider when select-ng the appropriate imaging procedure. Because there is aide range of radiation exposures associated with differ-

nt diagnostic procedures, a relative radiation level indi-ation has been included for each imaging examination.he relative radiation levels are based on effective dose,hich is a radiation dose quantity that is used to estimateopulation total radiation risk associated with an imag-ng procedure. Patients in the pediatric age group are atnherently higher risk from exposure, both because ofrgan sensitivity and longer life expectancy (relevant tohe long latency that appears to accompany radiationxposure). For these reasons, the relative radiation levelose estimate ranges for pediatric examinations are lowerompared with those specified for adults (Table 1). Ad-itional information regarding radiation dose assessmentor imaging examinations can be found in ACR Appro-riateness Criteria®: Radiation Dose Assessment Introduc-ion [46].

Disclaimer: The ACR Committee on Appropriateness Cri-eria® and its expert panels have developed criteria for deter-

mining appropriate imaging examinations for the diagnosisand treatment of specified medical conditions. These criteria areintended to guide radiologists, radiation oncologists, and refer-ring physicians in making decisions regarding radiologic imag-ing and treatment. Generally, the complexity and severity of apatient’s clinical condition should dictate the selection of appro-priate imaging procedures or treatments. Only those examina-tions generally used for the evaluation of a patient’s conditionare ranked. Other imaging studies necessary to evaluate othercoexistent diseases or other medical consequences of this condi-tion are not considered in this document. The availability ofequipment or personnel may influence the selection of appropri-

Note: Relative radiation level assignments for some of theexaminations cannot be made, because the actual patientdoses in these procedures vary as a function of a number offactors (eg, region of the body exposed to ionizing radiation, theimaging guidance that is used).

ate imaging procedures or treatments. Imaging techniques clas-sified as investigational by the FDA have not been considered indeveloping these criteria, but the study of new equipment andapplications should be encouraged. The ultimate decision re-garding the appropriateness of any specific radiologic examina-tion or treatment must be made by the referring physician andradiologist in light of all the circumstances presented in anindividual examination.
