Need assistance? Call Saint Lukeâs Concierge A venogram is a test that lets your healthcare provider see the veins in your body, especially in your legs. A special dye is injected that can be seen on an X-ray. The dye lets your healthcare provider see your veins and how healthy they are. A venogram is used to diagnose deep vein thrombosis (DVT) or other abnormalities of your veins.

- An angiogram is an X-ray image of blood vessels after they are filled with a contrast material. An angiogram of the heart, a coronary angiogram, is the gold standard for the evaluation of coronary artery disease (CAD). A coronary angiogram can be used to identify the exact location and severity of CAD.

Overview Coronary angiogram. Overview. A coronary angiogram is a procedure that uses X-ray imaging to see your heart's blood vessels. The test is generally done to see if there's a restriction in blood flow going to the heart. Coronary angiograms are part of a general group of procedures known as heart (cardiac) catheterizations.

Electrocardiography Electrocardiography (ECG or EKG[a]) is the process of recording the electrical activity of the heart over a period of time using electrodes placed on the skin. These electrodes detect the tiny electrical changes on the skin that arise from the heart muscle's electrophysiologic pattern of depolarizing and repolarizing during each heartbeat.

Venography A Venogram is an x-ray of the veins. It uses contrast dye and an x-ray camera (fluoroscopy) to visualize the veins. The veins are not visible under fluoroscopy without the use of the contrast dye. vascular system. Once the catheter is in the right position, a dye is injected into the veins.
