What is Wide Bore MRI?
A Wide Bore MRI is an imaging system that is open to comfortably accommodate all patients. This differs from the traditional tunnel-style magnetic resonance imager in which some patients feel confined and uncomfortable.
How should you prepare for the procedure?
MRI uses a strong magnetic field. Patients will be interviewed prior to the exam and asked if they have any metallic objects in their body. If there is any question of metal fragments being present, you may be asked to have an x-ray that will detect any such objects. In most cases, cardiac stents, artificial heart valves, prosthetic joints, and surgical staples, plates, pins and screws pose no risk during MRI if they have been in place for more than four to six weeks.
Ideal clothing should be worn for your MRI exam; clothing should not have any metal snaps, buttons, or zippers (e.g. sports bra, shorts or pants with elastic waste, jogging suits).
As with all radiological procedures patients should inform the technologist if there is any chance of pregnancy.
- You CANNOT have an MRI if you have a pacemaker, brain aneurysm clip more than 10 year old, middle ear or cochlear prosthesis
- You CANNOT have an MRI if you have a neuro stimulator or dorsal column stimulator
- You must advise the technologist if you have any prosthetic device (such as a knee or hip replacement)
- Do not wear any jewelry, hair ornaments, etc. All jewelry, earrings, watches, eyeglasses, etc. must be removed
- Pockets must not hold any wallets containing credit cards, coins, keys, cellular phone, etc. A lock and locker will be provided to you for personal belongings.

What can a person expect during the MRI study?
The patient is placed on a sliding table by the technologist and positioned comfortably for the study in the bore of the scanner. The technologist leaves the room and programs individual MRI sequences that typically last between 2 and 6 minutes each. A tapping or knocking noise will be heard during the imaging process. An intercom allows the patient and technologist to communicate with each other at any time during the study. Depending on the number of images necessary, the study will generally take 20-30 minutes. You will be asked not to move during each sequence while breathing normally.
Our MRI is equipped with magnacoustics communication and music system. There is an ipod docking station, CD, and radio available if you wish to listen to MUSIC while having your MRI exam. You are welcome to bring your own ipod or iphone, and/or music CD of your choice.
Depending upon the study, a contrast material (gadolinium) may be injected intravenously in an arm vein. This material will enhance certain tissues or blood vessels, making them more conspicuous and aiding diagnosis.
