Magnetic resonance imaging (MRI)

What’s an MRI?

MRI uses a strong magnetic field, radio waves and a computer to create high-resolution images of organs and other structures inside your body. Unlike X-rays and CT scans, an MRI doesn’t use radiation.

When is MRI used?

Your doctor may use MRI to:

• Assess blood flow.
• Assess injuries to bones and joints.
• Detect abnormal tissue hidden by bone tissue.
• Detect tumors and diagnose many forms of cancer.
• Evaluate infections.
• Examine chest, abdominal and pelvic organs and other soft tissues.

What to expect

A traditional MRI unit is a cylinder-shaped tube (bore) surrounded by a donut-shaped magnet. You’ll lie on a bed that slides into the center of the MRI machine. The machine may make tapping or clicking noises. You’ll need to be very still during your test so the MRI can get clear images.

Your technologist will control the scanner from a computer in another room and will be able to see you. You’ll be able to talk to each other through a two-way intercom.

Wide-bore MRI

Feel more comfortable during your imaging test with wide-bore MRI at ProHealth Oconomowoc Memorial Hospital or ProHealth Medical Group in Pewaukee. You’ll get high-quality images while benefiting from:

• Custom lighting and soothing music.
• Faster, quieter tests.
• Shorter, roomier tube (bore) that allows many tests to be done while your head remains outside the covered area of the machine.
