Angiogram

An Angiogram (pronounced: an-gee-o-gram) is a medical imaging technique used to visualize the inside, or lumen, of blood vessels and organs of the body, with particular interest in the arteries, veins, and the heart chambers. This is traditionally done by injecting a radio-opaque contrast agent into the blood vessel and imaging using X-ray based techniques such as fluoroscopy.

Etymology

The term "Angiogram" is derived from the Greek words Angio- meaning "vessel" and gram meaning "drawing".

Procedure

The procedure involves inserting a thin tube (a catheter) into a blood vessel in the arm or leg, and guiding it to the area to be studied. Once the catheter is in place, the contrast agent is injected and images are captured.

Types of Angiograms

There are several types of angiograms, including:

Risks and Complications

Like any medical procedure, an angiogram carries some risks. These may include bleeding, infection, allergic reaction to the contrast agent, and damage to the blood vessels. In rare cases, the procedure can cause a heart attack or stroke.
