What is MRI?
Magnetic Resonance Imaging, or MRI, is a diagnostic procedure that utilizes a powerful magnet and radio waves to produce detailed images of the body without the use of radiation.
Yeoh & Muranaka Radiology currently has two MRI units. The MRI Center of Hawaii is equipped with a 1.5T Toshiba Titan and the Open MRI of Hawaii is equipped with a .7T Hitachi Altaire Open MRI.
The Toshiba Titan features a 71cm aperture. This is the largest ultra-short bore magnet available in Hawaii. With Toshiba’s new Pianissimo technology, acoustic noise is reduced by up to 90% labeling the Titan one of the quietest MRI available.
The Hitachi Altaire Open MRI allows us to accommodate highly claustrophobic patients because of its open side design. The sides of the Altaire are open and the patient is not enclosed in a tube.

Once checked in, you will be provided with a gown to change in to and a secured locker for your personal items. The technologist will then guide you to the MRI scanning room. The MRI room has a strong magnetic field at all times, so for your safety the technologist will verify that you are not carrying any metal objects with you.
You will then be positioned on the scanner table and sensors will be placed around the region of interest. Pillows and pads will be used to assist in positioning your body for maximum comfort and optimal scans.
All contrast or combined exams require BUN, Cr, and GFR.
Do not eat or drink anything 2 hours prior to the exam.
You cannot have an MRI if you have:
- A Cardiac Pacemaker
- Brain Aneurysm Clips
- Foreign Body / Metal in Eyes
Please advise the technologist if you have any prosthetic devices (ie. hip or knee replacement). If patient requires tranquilizer, please plan to arrive 30 minutes prior to the appointment and be accompanied by a companion. All patients must remove all jewelry, hair pins and other metallic accessories for the procedure. Headphones and/or earplugs are available during most procedures.
