MRI - Magnetic Resonance Imaging
What is an MRI?
MRI (magnetic resonance imaging) is state-of -the-art technology that uses a computer, a strong magnetic field and radio waves to create a sophisticated, computer-enhanced image of a specific part of the body. This non-invasive procedure is a great way to see inside the body without exposing patients to ionizing radiation (x-rays). There are no known side effects of an MRI. It is more detailed and precise than an x-ray because it produces high-resolution images of the body and can provide important information about the brain, spine, joints, muscles, ligaments and internal organs. An MRI can lead to early detection of potential health concerns and assists doctors in making a diagnosis and planning treatment.
Why would I be asked to have an MRI?
Talk with your primary doctor about this. MRI's can be used to diagnose and monitor health concerns in various parts of the body, including the head, body, breast, heart and prostate.
How do I prepare for an MRI?
- You may go about your normal routine on the day of your MRI studies, including medication schedule, unless your doctor gives you special instructions.
- Metal interferes with the MRI equipment, so the technologist will ask you to remove anything metallic such as a hearing aid, hairpins, glasses, partial plate, jewelry, and clothing with zippers. We will furnish a locker for you to secure your personal items during the exam.
- Tell your doctor and the technologist before the MRI if you have a pacemaker, artificial heart valve, implanted drug infusion port, intrauterine device (IUD), or any pins, metallic implants, aneurysm clips, or metal fragments from previous injuries or surgeries.
What should I expect?
Before the scan, a technologist will assist you onto an automatic scanning table. It is important that you move as little as possible during the exam. The table will then slid every smoothly into the opening. You won't feel anything, but you will hear a bumping noise and humming of the machine. This is normal. A speaker is installed in the MRI unit which will allow you to communicate with the technologist during the procedure if you wish. Music can be played through these same speakers, so bring your favorite CD if you would like.
In some cases, the doctor may order a contrast (image enhancement) agent. This agent is injected into a vein in your arm. The contrast makes the details in the MRI images clearer and is standard for some types of MRI scans.
What about after my MRI?
After the exam, the radiologist and technologist will review the images to ensure diagnostic quality. If the quality of the images is acceptable, you may go home. If more images are needed, they will usually be taken right away. The radiologist will send your doctor a written report within 24 hours.
