What is this test?
CT angiography is an imaging test that uses computed tomography and intravenous contrast to take detailed pictures of blood vessels. It may also be used to assess the position and patency of a vascular stent. This test has been marked as deprecated in the test catalog.
Why might I need this test?
A clinician may order this test to evaluate a stent, investigate symptoms such as pain or reduced blood flow, or assess the appearance of nearby blood vessels. The information can help identify narrowing, blockage, or other vascular problems.
How is the test performed?
You will lie on a CT scanner while X-ray images are taken. Intravenous contrast is usually injected through a vein in your arm, and the scanner captures images of the relevant blood vessels before, during, and after the contrast is delivered.
How do I prepare for the test?
Follow the imaging center's instructions, which may include fasting or special medication precautions. Tell the care team about any prior contrast reaction, kidney disease, pregnancy, or implanted devices, and do not stop prescribed medicines unless your clinician advises you to do so.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Results may reveal narrowing or blockage of a blood vessel, problems with stent position or blood flow through the stent, or other vascular abnormalities. The findings should be interpreted by a radiologist in the context of your symptoms, prior procedures, and other tests. Abnormal-looking findings do not always have the same clinical significance for every patient.
Short name
Stent CT angiography with IV contrast
