What is an MRI?
An MRI, or magnetic resonance imaging, is a noninvasive test that uses a magnetic field, radio frequency and a computer to produce detailed images of internal body structures. These images help doctors see inside the body, aiding them in diagnosis and treatment.
A traditional MRI unit looks like a large tube surrounded by a magnet. Patients lie inside the tube during the procedure. Unlike an X-Ray or CT (computed tomography) scan, the MRI does not use ionzing radiation. While the patient is inside the magnetic field, radio waves send and receive signals that are detected by the electric coils that produce the magnetic field. These signals are sent to the computer and processed to generate detailed images of the body. Often, an MRI is better at revealing abnormal or diseased tissue that X-Ray's and CT scans.
What is an Open MRI?
An open MRI, also called a short-bore system, is designed so that the magnet does not completely surround the patient but is open on both sides. Patients love the fact that they no longer have to lay down and be in a tube for their MRI procedure. This machine is very accurate and comparing studies to our larger MRI, the studies are excellent. The benefit of this machine is the capabilities to perform scans for children and patients who are claustrophobic. The open MRI is capable of scanning knees, hands, wrists, elbows, foot and ankle joints. The procedure takes approximately one hour and is painless.
