What is an angiography?
Angiography is an exam of the arteries and veins to diagnose blockages and other blood vessel problems.






Types of Angiography

  • MR Angiography (Blood Vessels)
    MRA is a very useful way to detect problems with blood vessels and is an aid in determining how to best treat those problems.. If an ultrasound study shows that such disease is present, many surgeons will now do the necessary operation after confirmation by MRA, dispensing with the need for catheter angiography. MRA has also found wide use in evaluating patients for disease in the arteries of the brain, so that only those with positive findings will need to have a more invasive catheter study. MRA also is used to detect disease in the aorta and in blood vessels supplying the kidneys, lungs and legs. Patients with a family history of aneurysm, a ballooning out of a segment of the vessel wall, can be screened by MRA to detect an aneurysm that has not produced symptoms. If an aneurysm is found, it may be treated surgically, possibly avoiding serious or fatal bleeding.

  • CT Angiography
    CT (Computed Tomography) Angiography (CTA) is an examination that uses x-rays to visualize blood flow in arterial vessels throughout the body, from arteries serving the brain to those bringing blood to the lungs, kidneys, and the arms and legs. CTA is commonly used to examine the pulmonary arteries in the lungs to rule out pulmonary embolism, a serious but treatable condition. Also, identify dissection in the aorta or its major branches. It is also used to visualize blood flow in the renal arteries (those supplying the kidneys) in patients with high blood pressure and those suspected of having kidney disorders. Narrowing (stenosis) of a renal artery is a cause of high blood pressure (hypertension) in some patients, and can be corrected. Narrow detecting in the carotid arteries may then undergo cervical intervention to decrease risk of future stroke.
