MRI SAFETY WEEK!

By Norman McPhail

Welcome to MRI Safety Week! MRI Safety week was put in place to help educate both imaging centers & patients. Safety is always top priority for MRI centers but they can always do better. A few years back (2001), a patient in New York died due to a metal oxygen canister being drawn into the MRI where the patient was lying. With proper preparation, this accident should never have happened. MRI Safety Week will help make your next MRI (Magnetic Resonance Imaging) scan experience safer, easier and much more comfortable.

Research and preparation. An MRI is basically a large magnet that uses its magnetic field to produce pictures of your body’s organs and structures. The advantage that an MRI’s has over CT Scans or x-rays is that it does not emit cancer causing radiation, just a harmless magnetic field.
Before your MRI exam, do a little research so you know what to expect. The goal is to be prepared, no surprises. Learn about how an MRI works and what to expect. Knowledge will help to ease your anxiety. Ask your doctor details about why he wants the exam. What he is looking for. What MRI machine is best for your scan?

MRI Preparation. In preparing for an MRI, it is important to know that all metal objects must be removed from your body before entering into a scanning room. You must remove objects such as hearing aids, dentures, partial plates, keys, cell phone, glasses, hair pins, jewelry, piercings, watches, money clips, credit cards, coins, pens, pocket knife, just to name a few.

Drawbacks of an MRI. One of the biggest complaints about an MRI is that it is very loud. Ear plugs or music can help drown out the noise. Check with the imaging facility ahead of time to see if they have music you can listen to or if you can bring in your own music.
An additional complaint is that MRI’s are done in a confined space (23” wide tube). Some people are claustrophobic and don’t enjoy confined spaces. Even a healthy person being squeezed into a small tube and being forced to lie still for 20-30 minutes is very difficult.

Types of MRI Machines. A standard MRI exam takes place with you lying on a table inside a small tube. During the scan you must lie completely still for 20-30 minutes. Any movement can blur the results and you will have to re-do the exam.
For those who are claustrophobic, you can opt for an Open MRI. An Open MRI does not have a tube, but an open space to lie down on for the scan. A Stand-up MRI is also available (you can sit down as well) for patients that are unable to lie down. Finally, the Short Bore MRI. A Short Bore MRI works better with claustrophobic patients. The tube is 50% shorter and 5% wider than normal. Also, Short Bore machines only require part of the body to be inside the scanning tube. A high field Short Bore machine emits clearer pictures in the same amount of time.

MRI Quality. Tesla strength is important part of MRI quality. The Tesla strength is the strength of the magnet inside the MRI. Tesla strengths range from .3 all the way up to 3.0. The higher the tesla, the clearer the scan and the shorter the scan will take. But not all exams require a 3.0 tesla machine. Check with your doctor for his recommendation for type of MRI and strength that would be best for your scan.

MRI Exam with Contrast. An MRI exam may include contrast. Contrast is a dye that is injected to help enhance the scan. Contrast does cost extra. Contrast may be needed if the doctor is looking for cancer, tumor or the patient has had a previous surgery.
