What does CTPA mean in MEDICAL

CTPA stands for Computed Tomography Pulmonary Angiography. It is a diagnostic imaging test that uses x-ray technology to look for signs of blood clots in the pulmonary arteries.

During the procedure, a dye is injected into your veins and circulated through your body. As it passes through the lungs, special x-ray images are taken that reveal any blockages or narrowing due to blood clots or other causes.

CTPA can detect conditions such as deep vein thrombosis, which can cause serious complications if left untreated. It can also be used to diagnose possible causes of pulmonary embolism and identify blockages in arteries.

The procedure begins with an intravenous injection of dye into your veins. This will help provide enhanced images on the x-ray scans taken during the procedure. You may then be asked to lie still on your back while special x-ray images are taken from different angles.

There are few risks associated with this procedure. However, there may be some allergic reactions to the contrast dye used, so it's important to discuss any concerns you have prior to undergoing this procedure with your doctor.
