Final answer:
CT is known as computed axial tomography, CAT-scan, and computed tomography but not digital subtraction angiography, which is a separate imaging technique.
Step-by-step explanation:
Computed Tomography (CT), known commonly as computed axial tomography (CAT) or a CAT-scan, is a noninvasive medical imaging technique. This technique involves taking multiple X-ray measurements from different angles around the body and using computer processing to create cross-sectional images, or 'slices,' of the bones, blood vessels, and soft tissues inside your body. CT scans are used extensively in medicine to diagnose diseases, guide procedures, and plan treatments.
The correct answer to the question 'CT is commonly referred to as all of the following names except:' is b. digital subtraction angiography. Digital subtraction angiography is a separate imaging technique used to visualize blood vessels by processing images to subtract the anatomical background, leaving only the blood vessels visible.
