CT angiograms (CTAs) are a type of medical imaging technique that uses computed tomography (CT) technology to capture images of blood vessels in the body. CTAs are a non-invasive alternative to traditional angiography and can show your doctor important information about any blockages or conditions affecting your blood vessels.
CTAs work by using a specialized CT machine to capture multiple images of blood vessels, creating a three-dimensional (3D) view. CTAs can help diagnose and treat a variety of medical conditions including aneurysms, material stenosis, and pulmonary embolism.
