Computed Tomography and Computed Axial Tomography Scans
A Computed Tomography (CT) scan is a special type of X-ray procedure that uses a computer to combine many images to generate cross-sectional views of the body. Also called Computed Axial Tomography(CAT) scans, this type of imaging produces detailed photos of internal structures such as the heart, lungs, brain, blood vessels and bones.
A CT scan may be used for the following reasons:
- To diagnose brain tumors, cancer, or stroke
- To prepare for angiography
- To find blood clots in legs
- To perform renal angiograms for people with hypertension
- To find carotid stenosis and blockages
