Magnetic Resonance Imaging

Magnetic Resonance Imaging, or MRI, is an advanced, state-of-the-art diagnostic test, which produces very clear pictures or images of the human body without the use of X-rays. This technology enables physicians to detect developing diseases or abnormalities earlier than ever before. MRI uses a powerful – but harmless – magnetic field and radiowaves like the kind that transmit your favorite FM music. The combination of radiowaves and magnetic field produce detailed images of body structures such as the brain, the spine and other vital organs.

The Toshiba Titan MRI – Now Available at Roxborough Memorial Hospital

The Titan combines an ultra-short magnet and wide opening (gantry) to create a spacious and comfortable environment for patients. It also features “Pianissimo” technology, which reduces exam noise, to provide a quieter, more comfortable experience.

Patient Preparation

Prior to your exam, please review the following checklist:

Please bring previous X-rays applicable to the exam. The radiologist may want to review them. (For example, if you are having an MRI of your knee, bring any previous X-rays of your knee.)
In most cases, it isn’t necessary to refrain from eating and drinking before your scan. Your physician can guide you through the preparation for your specific exam.
You CAN take any medication you may currently be taking. It is not necessary to stop taking it prior to the exam. In fact, the exam will be much more comfortable if you continue to take your medication.
You CANNOT have the exam if you have any of the following:
- Certain cerebral aneurysm clips (magnetic)
- Certain heart valves
- Cochlear implants
- Metal filings in the eye
- Pacemaker/Defibrillator
You will be asked a series of questions concerning your surgical and occupational background. If this history includes metal work (ex. welders, grinders, etc.) or metal implants, please be sure to tell the technologist prior to your exam. Preliminary X-rays may need to be taken.
If you think you may be claustrophobic, ask your doctor to prescribe medication prior to the exam. If you do receive medication, please bring someone with you that will be able to drive you home because you will not be able to drive yourself.

Relax and do not worry about the exam. We will make sure that you receive the quality, professional care that you deserve.

During the Examination

Although MRI is a very advanced medical technique, the MRI scan is probably one of the easiest and most comfortable exams you will ever experience. The technologist will simply ask you to lie down on a cushioned table that will automatically move into the magnet after you have been comfortably positioned for scanning. The technologist will be in contact with you throughout the exam. When the MRI scan begins, you will hear a gentle tapping (versus the loud pounding you may hear in other MRI machines). Just relax – even take a nap – but try to lie as still as possible, since any movement during this time will blur the picture. Other than light sound, you should experience no other sensation during scanning. When scanning is complete, the technologist will return to assist you off the table.

The technologist may place an MRI coil around the part of the body to be scanned. Like an antenna, the closer the coil is to the area of interest on your body, the better the image quality of your exam.
