Computed tomography pulmonary angiography

Computed Tomography Pulmonary Angiography (CTPA) is a specialized imaging test that uses a CT scanner and a contrast dye to visualize the blood vessels in the lungs. It helps detect blood clots, such as pulmonary embolisms, by providing detailed, cross-sectional images of the pulmonary arteries. The procedure involves injecting the contrast dye into a vein, then taking rapid X-ray images as the dye travels through the lungs. CTPA is a valuable tool for quickly and accurately diagnosing blood flow issues in the lungs, guiding appropriate treatment decisions.
