The MRI suite’s two new scanners take Providence Regional’s MRI capabilities to a new level, with faster scanning speeds, higher quality images and the ability to accommodate larger patients.
GE Discovery MR750
The GE Discovery MR750 scanner makes routine exams faster and advanced exams routine.
It offers in-room patient setup in as little as 30 seconds and opens new neurologic scanning options for stroke and brain tumors.
The machine’s powerful magnet has twice the magnetic field strength of the MRIs previously used at Providence Regional. This means faster scans with higher quality images.
- Adjustable airflow and lighting enhance comfort for patients
- Patient anxiety can be reduced by being prepared outside the scan room on a detachable Express Patient Table
- Faster scanning

GE Discovery MR 450
The GE Discovery MR 450 provides ultra-high-resolution exams and increases patient comfort because its wide opening can accommodate larger patients or patients who may feel claustrophobic.

What is Magnetic Resonance Imaging (MRI)?
Magnetic Resonance Imaging, or MRI, is an imaging system that allows doctors to look inside the human body without the use of x-rays. MR imaging uses a large magnet, radiowaves, an antenna, and sophisticated computer processing to produce the images.
MRI can lead to the early detection of disease and its extremely precise images can reduce the need for surgery. It is used to diagnose:
- musculoskeletal problems
- brain and other nervous system disorders, such as stroke, traumatic injuries, and multiple sclerosis
How to prepare for MRI
No special preparation is usually necessary, however, you should be aware that any metallic object can interfere with the MRI magnet. You should not have this exam if any of the following are present:
- cardiac pacemakers
- cerebral aneurysm clips
- insulin pumps or other infusion pumps
- cochlear (inner-ear) implants
- other metal in the body, especially in your eyes
Please let both your doctor and the technologist know if you are claustrophobic. You may ask your physician for a prescribed sedative to make the procedure more relaxing. You can talk with the technologist over the intercom if you become anxious during the exam. Parents may stay with their child.
Plan on allowing one hour for the exam. If multiple areas of your body are examined, it may take longer. If you’ve had a sedative, you may be asked to stay a while afterwards. Otherwise, you may return to your normal activities.
How the procedure is performed.
After you’ve changed into a patient gown, the technologist will ask you to lie down on the table connected to the MRI machine. For some exams, a small coil (a radiowave receiver) may be placed over or under your body. A contrast agent via an IV may be used to highlight certain tissues. All contrast agents are FDA-approved and considered safe.
The exam begins as the table slides into the machine. You'll hear a loud thumping sound which is the result of the magnet working inside the machine. You'll need to remain completely still for most of the exam. To ensure that the images are not blurred, the technologist will occasionally ask you to hold your breath.
MRI uses no x-rays and the magnetic fields used during the exam are not harmful. However, as with any medical procedure, please let the technologist know if you are or may be pregnant. Any contrast agents used are not radioactive and should not cause any allergic reactions. Occasionally, however, a patient may react to the dye. The reaction is usually no more severe than a headache. Please let the technologist know if you've ever had reactions to contrast agents.
Your exam results are sent within two working days to your referring physician who will then contact you about your results.
