MRI

Lexington Medical Center’s two MRI units are used by physicians to obtain useful diagnostic information. With state-of-the-are technology, MRI produces images of the anatomy without the use of radiation required by other imaging technologies. The procedure is used to examine all parts of the body and is useful in the evaluation of conditions such as:

• brain disorders 
• traumatic injuries 
• eye abnormalities 
• spine diseases 
• tumor detection 
• liver and other abdominal diseases
• knee and shoulder injuries 
• musculoskeletal disorders
• facial/neck abnormalities 
• infection 
• cardiac malformations
• blood flow and vessel disorders

MRIs can be used as a primary diagnostic tool to provide a quick and accurate diagnosis for your physician. MRI is a non-invasive procedure with no known side or after-effects. The procedure is painless and you will not feel any sensations during the procedure. In fact, many patients find the procedure so relaxing they fall asleep during the exam.

There are two main types of MRI scanners High-field MRI and Open MRI. LMC has both of these technologies.

High-field MRI offers superior image quality due to the 1.5T magnet. The stronger magnet means shorter scan times per study, thus a shorter exam time for you. The LMC system also offers 2 High field short bore MRI machines at our Lexington and Irmo facilities. These combine the signal strength of a traditional high field with a larger bore for a more open feeling.

The open MRI at LMC is completely open on all four sides so you will not feel confined in any way. Its size can accommodate very large patients, and its openness is friendly to children.

Best of all, this advanced open MRI uses a more powerful magnet than all other “open-air” units.

As a result of the higher signal strength, pictures of the inner body are clearer, and show more detail, allowing doctors to diagnose medical conditions earlier and more accurately.

How does MRI operate?

MRI images are formed when signals, emitted by body tissue, are processed by software and turned into clinical images. These signals are generated using a safe magnetic field in combination with radio waves.

What should I expect?

A typical procedure averages 30 minute or longer depending on the type of information required by your physician. Prior to entering the scan room you will be asked to leave items that are not compatible with the magnetic field in a safe place. Some of these items include: 

• coins
• jewelry 
• earrings 
• watches 
• glasses 
• credit cards 
• hearing aides 
• keys 
• hair pins 
• other metal objects

You may also be asked to remove make-up and dentures and wear a hospital gown to avoid magnetic interference with belt buckles and zippers.

You can help make the image quality of your MRI the best it can be by simply relaxing and remaining as still as possible.

During your exam a MRI technologist will position you on a comfortably cushioned table. The Technologist will be with you and will be able to see you at all times. For your convenience, an intercom system is built into the scanner so you can make contact with your technologist if the need arises. In certain cases a contrast agent may be administered to enhance the study. There are no extra precautions that need to be taken if your physician requires this type of study.

Once the exam has begun you will hear a series of knocking sounds. These sounds are completely normal and represent changes in the magnetic field. Remember please try to remains as still as possible. When the exam is finished the Technologist will assist you off of the table and out of the scan room.

How do I prepare for the exam?

No special preparation is required prior to your MRI exam. You may eat normally and perform your daily routines without interruption. Continue to take any medications prescribed by your physician unless otherwise directed. If you are pregnant, please notify your physician prior to having your MRI exam.

Other items to consider are the presence of implants and similar items. Check with your physician or MRI technologist if you have had any brain, ear, eye, or other surgeries. Or, if you have any of the following:

• pacemaker 
• neuro-stimulator (tens-unit) 
• metal implants 
• intrauterine device (IUD), etc. 
• aneurysm clips 
• surgical staples 
• implanted drug infusion device 
• foreign metal objects in the eye 
• shrapnel or bullet wounds
• permanent eyeliner

How will my physician get the results?

After your MRI is completed, a Radiologist will study the exam by looking at the images on a computer using PACS or Picture Archiving & Communication System. The Radiologist will issue a report and a copy of that report will be sent to your physician. Your doctor’s office will then contact you with the results. Films of the exam can also be produced and sent to your physician.
