Unless you're told otherwise, you can shower and wash your hair the morning of your MRI. Don't use any hair products (such as hair spray or hair gel). Don't wear any metal objects. Remove all jewelry, including body piercings.

MRI is used to detect a variety of conditions, including problems of the brain, spinal cord, skeleton, chest, lungs, abdomen, pelvis, wrists, hands, ankles, and feet. In some cases, it can provide clear images of body parts that can't be seen as well with an X-ray, CAT scan, or ultrasound.

MRI is a medical application of nuclear magnetic resonance (NMR) which can also be used for imaging in other NMR applications, such as NMR spectroscopy. While the hazards of ionizing radiation are now well controlled in most medical contexts, an MRI may still be seen as a better choice than a CT scan.

You don't need to prepare for an MRI. Unless otherwise instructed, eat normally (before the procedure) and if you take medications, continue to do so. Once checked in, you'll likely change into a gown and robe. Remove all accessories, such as your watch, jewelry and hairpins.

The duration of the procedure will vary but the average is 45 minutes to one hour per body part. You will be required to lie still during the actual MR scanning. ... The magnet is permanently open on both ends. ... During the actual imaging, you will hear a loud intermittent banging noise.

Questions to ask your doctor How might this change my treatment options? Is there any reason why I shouldn't have an MRI scan? (If you have any implanted devices (such as a pacemaker, stents, an pump, or an artificial joint), be sure your doctor knows about them.)

How does MRI work? MRIs employ powerful magnets which produce a strong magnetic field that forces protons in the body to align with that field. When a radiofrequency current is then pulsed through the patient, the protons are stimulated, and spin out of equilibrium, straining against the pull of the magnetic field.

Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body.
