Angiogram Imaging of the Coronary Arteries
An angiogram is a type of medical imaging that allows a physician to see someone's arteries. In angiogram imaging, an X-ray contrast dye is injected into the arteries of interest, and fast-moving X-ray images, known as fluoroscopy, are monitored on a screen while the dye flows through the arteries. The series of images produced will reveal the flow of blood in the region, including any blockages or vessel abnormalities. Angiograms are commonly done with the arteries that supply the heart itself with blood, known as the coronary arteries. If blockage exists within these arteries, the patient may be at serious risk because if the heart itself does not have a supply of blood to function, it will not be able to effectively perform the job of pumping blood to the entire body.
