MR Arotography with Contrast (MRA)

Also known as Contrast Enhanced MR Angiography Aortogram

This test is for

Male, Female

Test Preparation

You may have to remove your jewelry and any metal objects which might interfere with the image.
Pregnant women should inform their doctor (and x-ray technician) as the radiations may affect the fetus. If needed, precautions can be taken to lower the radiation exposure to the fetus.
Get the blood urea and creatinine test done to evaluate kidney function and to ensure safety of contrast before taking up the procedure.

Understanding MR Arotography with Contrast (MRA)

What is MR Arotography with Contrast (MRA)?

MR aortography with contrast i.e. magnetic resonance imaging is a technique used to visualise the blood flow through the carotid artery (arteries which supply oxygenated blood to the head and neck) and intra-cerebral arteries (arteries which supply blood to the cerebrum). Gadolinium (a radio contrast material) is injected into the veins for better visualization of the blood flow through the arteries.

What is MR Arotography with Contrast (MRA) used for?

To diagnose vascular diseases of the brain like blockage in blood flow of the arteries which carries blood to the brain
To detect ischemic stroke (shortage of blood flow to the brain) and brain / spinal hemorrhage
To find out hematoma (accumulation of the blood behind the brain) and CVST (cerebral venous sinus thrombosis) where blood clot in the sinuses which drains from the brain.
To evaluate vascular malformation (includes congenital vascular abnormalities of only veins, lymph vessels, both veins and lymph vessels, or both arteries and veins
