Magnetic resonance imaging (MRI) is a medical imaging technique that uses a magnetic field and computer-generated radio waves to create detailed images of the organs and tissues in your body. Most MRI machines are large, tube-shaped magnets. When you lie inside an MRImachine, the magnetic field inside works with radio waves and hydrogen atoms in yo...
MRIis a noninvasive way for a medical professional to examine your organs, tissues and skeletal system. It produces high-resolution images of the inside of the body that help diagnose a variety of conditions.
Because MRI uses powerful magnets, the presence of metal in your body can be a safety hazard if attracted to the magnet. Even if not attracted to the magnet, metal objects can distort the MRI images. Before having an MRIexam, you'll likely complete a questionnaire that includes whether you have metal or electronic devices in your body. Unless the d...

You will typically be asked to change into a gown and to remove things that might affect the magnetic imaging, such as: 1. Jewelry. 2. Hairpins. 3. Eyeglasses. 4. Watches. 5. Wigs. 6. Dentures. 7. Hearing aids. 8. Underwire bras. 9....
During the test
The MRImachine looks like a long narrow tube that is open on both ends. You lie down on a movable table that slides into the opening of the tube. A technologist monitors you from another room. You can talk with the technologist by microphone. If you have a fear of enclosed spaces, called claustrophobia, you might receive a drug to help you feel sleepy and less anxious. Most people get through the exam without difficulty. The MRImachine creates a strong magnetic field around you, and radio wav...
After the test
If you haven't been sedated, you can resume your usual activities immediately after the scan.
A doctor specially trained to interpret MRIscans, called a radiologist, will look over the images from your scan and report the findings to your doctor. Your doctor will discuss important findings and next steps with you.
