MRI at Treasure Valley Hospital

MRI and what you should know:

Due to the strong magnetic field used during the exam, certain conditions may prevent you from having an MRI procedure. Some implants such as STENTS, SHUNTS, ANEURYSM CLIPS, PACEMAKERS, DEFIBRILLATORS, HEART MONITORS, NEUROSTIMULATORS, IMPLANTED DRUG INFUSION DEVICE, METALLIC FOREIGN BODY OR OTHER IMPLANTS may not be MRI compatible. If any of the following implants are applicable to you, please be prepared to provide the manufacturer and model number of the implanted device or an Operative Report from when device was implanted, either at the time of scheduling or prior to your exam. The radiology staff will let you know whether your implant is MRI compatible.

Preparing for your MRI:

Please arrive at least 15 minutes prior to your scheduled exam time. This is to ensure that you have enough time to fill out your registration paperwork. Wear comfortable clothing. Avoid wearing clothing with zippers, metal snaps or buckles. You will need to remove jewelry, watches, metal hairpins or clips, hearing aids, glasses and body piercings. There is usually no dietary or medication restrictions but a TVH imaging employee will inform you if there is. Most MRI scans take approximately 45-60 minutes per body part. However, it may take longer depending on what part of the body is being studied and if contrast is involved.

MRI exams with contrast:

Some MRI scans will require the use of a contrast dye, either through an IV or by an injection directly into the area being scanned. An MRI with the use of IV contrast is where you will have the contrast running through an IV during the duration of your scan. Make sure you drink plenty of fluids prior to having IV contrast. People who are PREGNANT, HAVE KIDNEY FAILURE, ASTHMA, DIABETIC OR HAVE EVER HAD A REACTION TO CONTRAST DYE will need to inform the technologist prior to your exam. A MRI with an injection is called an “MR Arthrogram.” If this is what you are having done, please see the section labeled “Arthrogram” for further instruction.

Claustrophobia:

It is important that you lie very still during your scan. If you think you or your family member will have difficulty lying still during the MRI scan, please discuss this with the doctor who ordered your scan. The physician may prescribe a mild sedative to help you relax. You will need a driver to drive you home if taking a sedative.
