MRI, or Magnetic Resonance Imaging, is a common medical imaging technique used for viewing the internal human anatomy in greater detail. Due to its capability to distinguish the various soft tissues, it is frequently used to examine the brain, musculature, or organs. Generating an image using magnets and radio waves, an MRI produces no radiation, making it completely safe. It is a painless, noninvasive procedure with no side or after effects.
Most MRIs require the patient to lie down in a tight, enclosed cylinder, which sometimes causes issues with those suffering from claustrophobia. At Dynamic Medical Imaging, we utilize the latest in MRI technology – the Fonar Stand Up. This unit is an open MRI scanner that allows a patient to sit or stand and watch television during the procedure. Most MRI tests last around a half an hour.
PREPARING FOR YOUR PROCEDURE
- Generally, no special preparations are required. You may follow your usual routine when it comes to eating, drinking and taking medications unless instructed otherwise by your physician, or our staff when scheduling your appointment.
- Certain types of scans involve the use of an injected contrast agent. If your doctor has ordered this type of scan, our staff members will explain about the contrast agent and answer your questions.
The only additional preparation for an MRI procedure is that all removable Metallic objects must be left outside the scanning room, including removable hearing aids, dentures and other prosthetic devices. You should leave all jewelry and watches at home.
- Credit cards cannot be brought into the scanner room since the magnetic codes on them can be affected by the magnet.
For optimal image quality, when performing head scans, all makeup must be removed since it may contain metallic powders, which are magnetic and thus degrade the image quality. It is VERY IMPORTANT to notify the technician if you have a pacemaker, think you may be pregnant or have a medical constraint that could interfere with the procedure. Also, it is VERY IMPORTANT to notify the technician if you are/were a machinist, welder, auto mechanic or work with metal in any capacity.
You should let the technician know if you even suspect you have anything metallic within your body such as surgical clips, joint or bone pins, metal plates, un-removed bullets, shrapnel, BB shots, cochlear implants, neuro-stimulators or permanent tattoos. These items may interfere with the procedure.
- You should wear comfortable clothing with no metal (zippers etc.). You may be asked to change into a gown for the exam.
