Ask a question


A coronary angiography is a medical imaging technique specialized in the visualization of the coronary arteries. It involves the injection of a contrast medium via an artery (often the femoral or radial), mostly of iodine in the absence of allergy, then an X-ray of the arteries. A coronary angiography enables the identification of disorders involving the coronary arteries and is systematically practiced in cases of myocardial infarction to locate the arterial stenosis involved.
