MRI (Magnetic Resonance Imaging)

Contraindications to MRI include pacemakers, aneurysm clips, certain artificial heart valves, and cochlear implants. We additionally screen for metallic fragments in eyes, imbedded metal foreign bodies and surgically implanted wires in the body. We also need to know if the patient has history of severe renal failure and is on dialysis. The technologist will have the patient complete a screening questionnaire at the time of exam and will ask certain questions to make certain that the MRI is a safe exam for the patient.

In general, it is best to have patients leave jewelry and hairpins at home since they may be asked to remove them for the exam. Dressing in comfortable clothes (preferably without zippers and snaps) is advised although we have gowns for patients to change into depending upon the exam being done. We have lock boxes where patients can secure their belongings.

Our exam times range from 30 to 60 minutes per exam. Most exams do not require a prep; however we ask abdominal exam patients to try to abstain from eating or drinking for 8 hours prior to exam. They may take medications with water if necessary.

Claustrophobic patients need to speak to their referring physician for medications. We do not dispense these. Keep in mind that the Open MRI will not necessarily 'cure' claustrophobia and meds may still be necessary.

Some exams require the administration of an IV contrast agent. We do not require lab work for this unless the patient gives a history of severe renal impairment.
