What is an angiogram?
An angiogram is a diagnostic procedure that uses X-ray images to look for blockages or narrow spots in your blood vessels (arteries or veins). An angiogram test can show how blood circulates in blood vessels at specific locations in your body. Healthcare providers use an angiogram of your heart, neck, kidneys, legs or other areas to locate the source of an artery or vein issue.
Your healthcare provider may want to do an angiogram procedure when you have signs of blocked, damaged or abnormal blood vessels. An angiogram test helps your provider determine the source of the problem and the extent of damage to your blood vessels. (Source: Cleveland Clinic link below)
