What do you need to know about a MRA scan?
The MRA machine combines radiofrequency waves with a strong magnetic field to generate images with incredible detail of your body’s blood vessels. MRA scans are most often used to take a look at the vessels in your neck, kidneys, legs, and brain.
How does a magnetic resonance angiography ( MRA ) work?
An MRI uses radio waves, a magnetic field, and a computer create a scan of your body to look for health problems. Magnetic resonance angiography (MRA) is a type of MRI. It looks just at the body’s blood vessels.
What does MRA stand for in medical terms?
MRA stands for magnetic resonance angiography and is a medical test that helps doctors diagnose medical diseases and conditions of the blood vessels so they can treat them. In MRA, radio frequency waves, a powerful magnetic field and a computer create detailed images of your body’s major arteries.
How is MRA used to diagnose renal failure?
There is no exposure to radiation with MRA. The contrast dye used in MRA is non-iodine and has much less toxicity. MRA can be used in individuals who are unable to tolerate the dye (either renal failure or allergy). MRA can identify the blood vessel disease, its severity and hopefully, decrease unnecessary surgery.
How is the MRA similar to the MRI?
The MRA (magnetic resonance angiography) is related to the MRI in that it uses MRI technology. The MRA itself is a minimally-invasive procedure done not just to identify problems in the body but also to treat them. You can learn more about the MRA here.
How does a magnetic resonance angiogram ( MRA ) work?
Magnetic resonance angiography–also called a magnetic resonance angiogram or MRA–is a type of MRI that looks specifically at the body’s blood vessels. Unlike a traditional angiogram, which requires inserting a catheter into the body, magnetic resonance angiography is a far less invasive and less painful test.
