An angiogram is a scanned image of blood vessels in your body. Angiography is a medical imaging technique that produces an angiogram.
Blood vessels do not show up in the normal scans. So, a dye is injected before starting the procedure to highlight the blood vessels in the scanned image.
Angiograms can be useful in diagnosing medical conditions such as atherosclerosis, peripheral arterial disease, brain aneurysm, blood clots, pulmonary embolism, etc.
