Doctors use angiography to diagnose and treat blood vessel diseases and conditions. Angiography exams produce pictures of major blood vessels throughout the body. In some cases,contrast material is used.
Doctors perform angiography using:
1.x-rays with catheters
2.computed tomography
3.magnetic resonance imaging
In angiography catheter , a thin plastic tube, called a catheter, is inserted into an artery through a small incision in the skin. Once the catheter is guided to the area being examined, a contrast material is injected through the tube and images are captured using a small dose of ionizing radiation (x-rays).
