CT SCAN / CTA
What is a CT?
Computerized Tomography (CT), also known as Computerized Axial Tomography (CT or CAT Scan), is a painless diagnostic procedure using low amounts of radiation to generate a sequence of highly detailed images. A computer then takes these images and compiles them into complete cross-sectional images (“slices”) of the area of the body being scanned. CT scans help radiologists to diagnose most cancers, cardiovascular disease, infectious diseases and trauma. We utilize a Multi-Slice Toshiba Aquilion CT scanner. This multi-slice scanner allows for a more comfortable exam, reduced waiting time, and a more accurate diagnosis than previous generation CT units.
What is a CTA?
Computed Tomography Angiography (CTA) is a diagnostic CT exam used to visualize the blood flow in the arteries and veins throughout the body. Unlike conventional angiography, CTA is a much less invasive procedure. It is commonly used to image abnormalities of the blood vessels and aneurysms.
