CTAngiogramm

CTAngiography, often abbreviated as CTA, is a non-invasive medical imaging technique used to visualize the blood vessels and detect blockages or abnormalities. It combines computed tomography (CT) with contrast agents to enhance the visibility of blood vessels. CTA is commonly used to diagnose and evaluate conditions affecting the arteries and veins, including coronary artery disease, peripheral artery disease, and venous disorders.

The procedure involves injecting a contrast agent into the patient's bloodstream, which is then detected by a CT scanner. The scanner produces multiple cross-sectional images of the body, which are reconstructed into a three-dimensional model. This model allows healthcare professionals to assess the structure and function of blood vessels, identify any obstructions, and evaluate the extent of damage.

CTA is particularly valuable in the evaluation of the coronary arteries, as it provides detailed images of the heart and its blood supply. It is also used to assess the blood flow in the extremities, detect deep vein thrombosis, and evaluate the blood vessels in the brain and abdomen. The procedure is generally considered safe and has a low risk of complications, although some patients may experience allergic reactions to the contrast agent.

CTA is typically performed on an outpatient basis and requires minimal recovery time. The results are usually available within a short period, allowing for prompt diagnosis and treatment planning. However, the interpretation of CTA images requires specialized training, and the results should be reviewed by a radiologist or other qualified healthcare professional.
