Angiography examinations produce pictures of major blood vessels throughout the body and can be performed with one of three imaging technologies and, in some cases CONTRAST material is administered.

MR angiography does not use ionizing radiation (x-rays). MRA may be performed with or without CONTRAST material. If needed, the CONTRAST material is usually administered through a small intravenous (IV) catheter placed in a vein in your arm.
