All About MRI’s-Part 1 -What an MRI Is
By:Liana Mirkin
Magnetic resonance imaging is a procedure in which radio waves and a powerful magnet linked to a computer are used to create detailed pictures of areas inside the body.
Because the MRI requires specialized equipment and expertise to perform it properly, the MRI frequently makes it possible to determine the cause of chronic back pain. The anatomy of the vertebrae that make up the spine, and the spinal cord can be seen in the exam as well as the spaces between the vertebrae through which nerves pass.
The ability to visualize normal and diseased tissue in the spine (also called the "vertebral column" or "backbone"), the bony structure that encloses the spinal cord is greatly increased as the result of this procedure.
The MRI Equipment Itself:
In most MRI units there is a closed, cylinder-shaped compartment which requires the patient to lie still for several minutes.
Some MRI machines (called "open" MRI) are less confining are made in such a way that the magnet does not completely surround the patient. Although they are useful for patients that are claustrophobic or obese, the strength of these open magnets is generally less than closed magnets and produces lower quality images.
