Magnetic Resonance Angiography (MRA)
MRA studies are non-invasive diagnostic tools used to assist in the diagnosis and treatment of conditions and diseases of the blood vessels. High quality images are acquired without the use of ionizing radiation and may be acquired with or without the use of contrast administration. MRA studies are very useful in identifying abnormalities in major arteries.
Renal
Useful in evaluating the renal arteries for flow defect.
Indications for Renal MRA
- Renal Vascular malformation
- Hypertensive chronic kidney disease
- Atherosclerotic renal artery stenosis
- Renal artery aneurysm
- Renal artery dissection
Brain
A very useful diagnostic tool in the diagnosing of blood vessel abnormalities in the brain; aneurysms are most commonly assessed. Contrast administration is not normally required to diagnose.
Carotid
This procedure is very useful in identifying areas of narrowing or wall damage in the carotid arteries in the neck. This may be done with or without contrast administration.
Upper and Lower Limbs
Indications of lower limb MRA
- Peripheral arterial occlusive disease
- Post-operative and stent evaluation
- Arterio-venous malformation
- Chronic critical ischemia
- Chronic arterial disease
- Runoff disease
- Acute arterial disease
Indications of upper limb MRA
- Arterio-venous Malformation
- Brachial Artery dissection
- Brachial vein thrombosis
- Brachial artery stenosis
- Atherosclerotic disease
- Aneurysms
- Vasculitis
