CT ANGIOGRAPHY RENAL VESSELS

Angiography is a minimally invasive medical test that helps physicians diagnose and treat medical conditions. Angiography uses one of three imaging technologies and, in most cases, a contrast material injection is needed to produce pictures of blood vessels in the body. It is performed using: x-rays with catheters, computed tomography (CT), magnetic resonance imaging (MRI). CT angiography uses a CT scanner to produce detailed images of both blood vessels and tissues in various parts of the body. An iodine-rich contrast material (dye) is usually injected through a small catheter placed in a vein of the arm. A CT scan is then performed while the contrast flows through the blood vessels to the various organs of the body. After scanning, the images will be processed using a special computer and software and reviewed in different planes and projections. This procedure is commonly used for body parts like brain, neck, heart, chest, abdomen and for conditions like aneurysms, blockages, atherosclerotic plaques etc.
