Arteriogram or arteriography involves injection of contrast material into one of the arteries so as to get X ray image of the blood vessel to determine narrowing of arteries. An arteriogram is also called an angiogram.This diagnostic test is used to detect vascular conditions like aneurysm, stenosis or blockage.
Angiograms can be specific to the blood vessels that are being examined, such as cerebral Angiography, renal angiography, aortography or Cardiac Catheterization. Coronary Angiogram or Catheter Angiogram is a minimally invasive procedure where a catheter is inserted into one of the arteries or veins. An IV line is inserted into a blood vessel of either the arm, neck or chest. A catheter is inserted though the IV and contrast material is injected into the desired vein or artery that has to be viewed. A series of x-rays are taken. The contrast material in the blood vessels causes them to appear opaque on an x-ray. There is a small risk of arteriogram leading to blood clots or bleeding and infection at the IV site.
Non invasive 64 slice CT (Computed Tomography) Angiogram (64 MSCTA) can identify the presence of early atherosclerotic plaque deposition before it shows up in the conventional catheter angiogram. Multi slice CT Angiogram can differentiate between various types of plaques - calcified, soft or mixed type. CTA of the multi slice scanners allows faster and comprehensive assessment of arterial blocks and is an important tool in the evaluation of stroke patients - as it enables effective diagnosis of cervicocranial vascular pathologies such as carotid artery stenosis. A 64 slice CT scan images may be pieced together to reveal 3 D images for extracting additional information.
