Computed Tomography (CT or CAT scan) Computed Tomography (CT or CAT scan) equipment equipment
Normal head CAT scan with intravenous contrast. Normal head CAT scan with intravenous contrast.
Coronal CT scanAxial CT scans
• Normal trachea. Normal trachea.
• CT scan shows normal trachea. The tracheal wall is CT scan shows normal trachea. The tracheal wall is seen as a soft tissue stripe measuring 1-2 mm in seen as a soft tissue stripe measuring 1-2 mm in thickness. The anterior and lateral walls are formed thickness. The anterior and lateral walls are formed by horseshoe-shaped cartilaginous rings, which by horseshoe-shaped cartilaginous rings, which frequently calcify with age. The posterior wall frequently calcify with age. The posterior wall consists of a fibromuscular membrane.consists of a fibromuscular membrane.
CT angiogram. Frontal or coronal view of chest-3D CT angiogram. Frontal or coronal view of chest-3D slab image showing pulmonary vessels. slab image showing pulmonary vessels.
• Maximum intensity projection reconstruction. Maximum intensity projection reconstruction. • Cross-sectional contrast-enhanced CT scan shows the main (MPA), Cross-sectional contrast-enhanced CT scan shows the main (MPA),
