Magnetic Resonance Imaging (MRI)
We offer patients the most advanced capabilities available on our 3T MRI scanner.
MRI creates pictures of your body using a magnetic field, radio waves and a computer. MRI pictures show bone and soft tissues of the body including; muscles, nerves, brain, discs and ligaments. An MRI scan is a painless procedure with virtually no known side effects.
What does 3T mean?
The strength of an MRI scanner is measured in units called Tesla (T) units, and MRI scanners can have a Tesla strength of 1T to 3T. Parkview Imaging Center’s MRI scanner has a Tesla strength of 3T, which is the most powerful MRI strength available for clinical use. The stronger the MRI strength, the faster the MRI scan can be done; and at Parkview Imaging Center, most exams take 20 minutes or less. 3T MRI scanners also take pictures of your body at the highest resolution available, meaning your doctor will see the highest level of image quality when seeing the MRI performed at Parkview Imaging Center. You might make the comparison to the picture quality of a regular TV compared to HDTV.
What happens during an MRI Scan?
The technologist will position you on the MRI scanner table and move the table into the MRI scanner. Although the technologist will be controlling the procedure from an adjacent room, he or she will be able to see and communicate with you at all times.
During the scan, you will hear a series of pulsing noises that sound like knocking or banging. These are normal sounds produced by the equipment. During most procedures, you will be able to use a headset to either listen to music or watch your favorite TV show during the exam.
What is a Contrast MRI Scan?
In a contrast scan, a clear nonradioactive liquid will be injected into a vein, usually in your arm. This contrast agent makes certain details clearer and is a routine part of some MRI scans. If your doctor orders a scan with contrast, you will need to drink plenty of fluids for the remainder of the day of your scan.
How do I prepare for my MRI Scan?
In most cases, you don’t have to do anything to prepare for your MRI scan. Unless you are instructed otherwise, you may eat and drink as you choose, and you can continue to take any prescribed medications.
Scans that require special instructions are those with contrast, and those done of the abdomen or pelvis. This is important to ensure high quality pictures. Please check with facility for specific instructions.
Before the scan, you will be asked to remove your watch, keys, coins, credit cards, hairpins, and any other objects that could be damaged by the MRI scanner or might cause distortion on the images. It is very important not to bring any metal objects into the scan room without letting the technologist know.
You may also be asked to change into a comfortable scrub top or bottom during your exam.
Can anyone have an MRI?
- Most patients can have an MRI exam, even those who have metal implants.
- Those patients with the following cannot have an MRI:
- Some inner ear implants
- Active Implanted neurostimulators or pain pumps
- Implanted TENS units
- The following implants may require that we see your implant card so that we can call the manufacturer for scanning safety:
- Cerebral aneurysm clips
If you should have any questions regarding the safety of any implant you may have, please feel free to call and speak to one of our technologists.
What if I am pregnant?
If you are pregnant or feel you may be pregnant please call us so we can consult with your physician and discuss the situation with you.
What If I am claustrophobic?
Parkview Imaging Center has many options to make you comfortable during your MRI scan. Most scans take less than 20 minutes to complete. Our theatre and sound system allow you to choose between listening to your favorite kind of music or watching your favorite TV show. In the most anxious patients, oral sedation can be used.
What happens after the test?
After your scan, the technologist will check to make sure quality images have been obtained. The radiologist will interpret the images and a report will be sent to your physician with the results of your MRI scan. Your physician will then discuss the results with you.
