What is diagnostic computed tomography?
Computed tomography is commonly referred to as a CT scan. A CT scan is a diagnostic imaging procedure that uses a combination of X-rays and computer technology to produce images of the inside of the body.

What is the principle of angiography?
Egas Moniz and J. P. Caldas began performing cerebral angiography. They used sodium iodide as the contrast agent and the radiocarousel to image the vascular system of the brain. The radiocarousel, which was invented by Caldas, could image at the rate of one image per second for a maximum of 6 s. Simultaneously, B.
What is the angiography test?
Angiography is a type of X-ray used to check blood vessels. Blood vessels do not show clearly on a normal X-ray, so a special dye needs to be injected into your blood first. This highlights your blood vessels, allowing your doctor to see any problems. The X-ray images created during angiography are called angiograms.
What is the difference between CTA and CT with contrast?
CT angiogram (CTA) can be used to view arteries and veins. Contrast dye injected into the bloodstream helps the computer “see” the vessels.
Why is computed tomography important?
Why are CT scans important? CT scans are a valuable diagnostic tool. They are able to detect some conditions that conventional X-rays cannot because CT scans can show a 3D view of the section of the body being studied. CT scans are also useful for monitoring a patient’s progress during or after treatment.
