Blood vessels form a complex network throughout your body, supplying vital oxygen and nutrients to your organs and tissues. When blood flow is restricted in these vessels, it can lead to various health problems.
Magnetic Resonance Angiography, or MRA, is a specialized MRI technique that uses strong magnetic fields and radio waves to create detailed images of blood vessels. Unlike traditional x-ray angiography, which involves inserting a catheter into an artery and injecting contrast dye, MRA is a non-invasive procedure.
MRA offers a clear view of your blood vessels, allowing your healthcare provider to diagnose various conditions affecting blood flow.
- Renal Artery Stenosis: The renal arteries supply blood to your kidneys. MRA can assess these arteries for narrowing, a condition known as renal artery stenosis. Narrowed arteries can restrict blood flow to the kidneys, potentially leading to high blood pressure and kidney problems.
- Mesenteric Ischemia: This condition occurs when blood flow to the intestines is restricted. MRA can evaluate the blood vessels supplying the intestines, aiding in the diagnosis of mesenteric ischemia. Early diagnosis and treatment are crucial to prevent tissue damage and serious complications.
- Other Vascular Conditions: MRAs can also be used to evaluate blood vessels in other parts of the body, such as the brain and neck. For instance, MRA can help diagnose conditions like carotid artery stenosis, a narrowing of the arteries that supply blood to the brain, which can increase the risk of stroke.
