At the Spine and Brain Imaging Center our MRI machine can be configured to perform a magnetic resonance angiography (MRA). MRAs have the ability to examine vascular tissues (blood vessels) and are used to diagnose aneurysms and carotid disease.
MRA images are produced by special computer, which has the ability to translate information generated from the MRA machine’s magnetic field and radio waves, into images of your blood vessels.
A contrast enhancing dye administered through an IV into your arm may be used in order to enhance and improve the quality of the MRA image. Most patients do not experience any sensations caused by the contrast agent, but some have reported brief flushed feelings, itching, or nausea. If these sensations do occur they should dissipate quickly.
At SBIC, convince and accurate results are a top priority. To make visits smooth and uncomplicated, Dr. Arvind Ahuja can see new patients during clinic hours and order an MRA scan immediately after the appointment. MRA tests may take 1-2 hours, with accurate results often delivered within 12-24 hours.
The staff at the Spine and Brian Imagining Center have a vast experience administering MRA scans with the goal of keeping patients as comfortable as possible, and will answer any questions you may have during the procedure.
What are MRAs used to Diagnose?
MRAs can be used to diagnose a variety of conditions caused by blood vessel abnormalities in the brain, neck, and chest. And can be critical in identifying cerebral aneurysms, blood clots, and weak or narrow blood vessels.
Dr. Ahuja may also request MRA tests to be done in order to prepare for surgery or to check the condition of blood vessels after a surgery is performed.
What are the differences between an MRI and MRA?
Since MRA scans are performed by making adjustments to our MRI machine, the process of the two imaging techniques are very similar. The results of the two tests produce different images. MRIs create detailed images of internal organs, tissues, and bones, which MRAs create images of specific arteries and blood vessels.
Many times patients may be requested to under go both MRI and MRA tests.
Is there radiation exposure from MRA scans?
MRAs do not use ionizing radiation, instead MRAs use a combination of a magnetic field and radio waves. During the imaging test there is no exposure to radiation and no cause for concern during the painless procedure.
If you are feeling anxious about your MRA scan, headphones and music are available, and in some circumstances intravenous sedation is available.
