What is MRI?
MRI, or magnetic resonance imaging, is a no ninvasive 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 specifica lly on your arteries.

What does an MRI machine look like?
Above you will see two types of MRI machines: a regular MRI scanner and the Open MRI scanner. The regular MRI scanner is a large cylinder-shaped tube surrounded by a circular magnet with a table that moves into and out of the magnet. The Open MRI scanner is open on both sides and does not completely surround the patient.
