Magnetic Resonance Imaging

Tuesday, May 23, 2017

Magnetic resonance imaging is a test that uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the body. Dr. Edward Hill discusses MRI in todays 60 Second Housecall.

Dr. Hill:

Magnetic resonance imaging, or MRI, is a non-invasive procedure that uses powerful magnets and radio waves to create detailed images of the organs and tissues within your body.

Unlike conventional X-rays and computed tomography, scans that use radiation, MRI imaging is based on the magnetic properties of atoms.

MRI provides an unparalleled view inside the human body. It is ideal to help diagnose many types of injuries and conditions because of the ability to tailor the exam to the particular medical question being asked.

Because MRI uses radio waves, the scanner must be located within a specially shielded room to avoid outside interference. The patient is asked to lie on a narrow table, which slides into a large tunnel-like tube within the scanner.

The patient doesnt feel the magnetic field or radio waves. The only possible discomfort is the claustrophobic feeling that some people experience from being inside the scanner. Because of the powerful magnetic field, patients with implanted pacemakers and other devices should not have an MRI.
