MRI examinations are very safe for most people; however, because of the very h3 magnet used, some people cannot enter the MRI machine for their own safety. MRI should NOT be used for patients with: pacemakers, cochlear implants, indwelling medication pumps, certain types of cerebral aneurysm clips, metal fragments in the eyes and some metallic hardware. For your safety, the presence of certain metallic objects must be determined before entering the exam room and may need to be removed (e.g., jewelry, eyeglasses, or hairpins). Inside the bore of the MRI, the space is small so if you are claustrophobic or think you may be, you may need pre-medication, an open MRI, or MRI may not be for you. If you are, or may be, pregnant, please discuss this with your doctor before booking an MRI. There is no evidence that MRI can harm a developing fetus, but the risk must be evaluated.
Contrast may need to be injected for certain MRI exams. Please see the If Contrast is Used section for further information regarding the use of IV contrast.
