Femoral angiography is a contrast X-ray technique, sometimes combined with MRI, that is used to diagnose narrowing or blockage of arteries in the legs. During the procedure, which is carried out under local anaesthesia, a contrast medium is injected into the femoral artery. The medium spreads in the circulation to other vessels in the leg. X-rays are then taken of one or more sites. The procedure takes about 30 minutes, and you should be able to return home within 6 hours.
