MRI utilizes magnetic fields and radio waves to obtain extremely detailed images of the body. Unlike x-ray, MRI provides images of soft tissue and muscle in addition to bones without the use of radiation. Another benefit of MRI is that images can be obtained at any plane and angle in the body-up and down; left and right; front to back. Through such images, injuries, tumors, hemorrhages and other anomalies can be detected.
"I think it is because of the high definition images and non-invasiveness of the procedure that patients appreciate receiving an MRI," says Chery Keen, MRI Senior Technologist at the Grey Nuns.

"People know that when they have MRI scans done, it can provide a diagnosis for them without using radiation." Set in a bright room, the blue and white unit is open on both sides. "Often people think they are going to go into a deep, dark tunnel," says Chery. "That's not the case at all. We try to make patients as comfort¬able as we possibly can. We know that it is a stressful time for them."

Each MRI exam takes between twenty and sixty minutes. Once a patient's images are obtained, a radiologist inter¬prets them and a report is then sent to the patient's doctor. "Working with the patients, providing good quality care, is the most rewarding part of my work," says Chery. "These examinations assist in the patient's treatment. I have many hopeful days knowing that."

Quick facts

• The magnetic field of an MRI is 30, 000 times that of the earth.
• The strong magnetic fields in an MRI unit would accelerate a paper clip at 40 miles per hour if it were in close proximately 110 decibels.  As a comparison motorcycles can generate noise up to 70 decibels.
