What is Magnetic Resonance Imaging (MRI)?
MRI technology that allows your doctor to look at your internal anatomy. No ionizing radiation is involved, but rather, a very safe but powerful magnetic field with radio waves.
What can I expect during my exam?
MRI makes a lot of noise. We provide music or ear plugs for your comfort. The approximate time will be anywhere from 25-45 minutes. Our scanner is short bore, so it is wider and shorter than most MRI machines, to make your experience better.
The scanner is wide open on both ends, well-lit and ventilated throughout. A microphone is built into the scanner so we can hear you at all times. We will also be providing a call button to hold that lets us know if you need assistance.
How should I dress for my MRI?
Please wear comfortable clothing without snaps, metal objects or zippers. You will be asked to put on a hospital gown during the exam. A locker will be provided for your belongings.
Is MRI safe?
MRI does not use ionizing radiation or X-ray. It uses a magnetic field and radio waves to create detailed images of the body. However, the presence of metal in your body may be a safety hazard or affect the MRI image. Before your MRI, be sure to tell the technologist if you have any metal or electronic devices in your body, such as:
- Artificial heart valves
- Implantable heart defibrillator
- Metal clips
- Cochlear implants
- Bullet, shrapnel or any other type of metal fragment
What should I do if I have had surgery in which metal has been implanted?
If you have had a surgery where metal was implanted be sure to inform your technologist before your exam. Implants that are placed by a surgeon have a manufacturer name and model number. Some surgeons provide a card with this information to their patients.
- If you have the following, you should not have an MRI:
- Certain aneurysm clips
- Certain implants that are not MRI safe
- Certain neurostimulators
Why is it important to remove all metallic objects before I enter the MRI scanning room?
Removing all metal objects is for your safety and to prevent these items from causing artifacts to appear on the MRI image.
Is it safe to have an MRI when pregnant or breastfeeding?
Before scheduling an MRI, tell your doctor if you think you’re pregnant. The effects of magnetic fields in the first trimester on fetuses aren’t well understood. Your doctor may recommend an alternative exam or postponing the MRI. You must sign a waiver.
If you are breastfeeding and are having contrast as part of your exam, please suspend nursing for the next 48 hours after your exam.
How do I get results?
After your MRI, the images will be reviewed by a radiologist who will issue a detailed report. A physician will make every effort to call you within 2-3 business days following your MRI.
