What is MRI?
MRI, or magnetic resonance imaging, is a non-invasive procedure used to provide images of the body’s internal structures. MRI uses a magnetic field, radio waves and a computer to generate clear, exceptionally detailed “pictures” of the area of interest, without using radiation. It is a painless procedure.
An MRA, or magnetic resonance angiography, is simply an MRI that focuses specifically on your arteries.
