What is MRI?
Magnetic resonance imaging and Magnetic Resonance Angiography are performed using a strong magnetic field to generate images of the body. A powerful computer is used to create these images which are reviewed by a Technologist during the exam and interpreted by one of our Radiologists.
There are no x-rays involved in the use of MRI, which makes the exam safe with no known adverse effect of magnetic and radio waves. Common areas of study include brain, spine, neck, breast, abdomen, muscles, soft tissues and joints. Desert Valley Radiology utilizes a 1.5 Tesla Signa High-Field MRI by GE.
Preparing for an MRI
There is no specific preparation required for MRI, although you should avoid eating or drinking caffeine prior to your exam.
Certain health conditions or metallic implants may prevent you from having an MRI. Be sure to inform your physician or our staff if you have any of the following:
- Brain aneurysm clips
- Infusion pumps such as for insulin or pain control
- Cochlear implants (inner ear)
- History of working with metals
- Pregnancy in the first trimester
- Recent vascular stent (within 6 weeks of placement)
What should you expect?
In order to perform an MRI scan, you will be asked to remove any clothing or jewelry with metal parts, and you may be asked to change into a patient gown.
During the exam, you will lie on a comfortable table that will slide on a track into the scanner. A special coil may be used which will be placed around the area of your body to be scanned and will help isolate the imaging procedure.
If Magnetic Resonance Angiography has been ordered by your physician, a contrast material with be administered through an IV in your arm. MRA is used to higlight certain blood vessels in the body to identify areas of narrowing.
Once the exam begins, a Technologist will be able to talk to you through a microphone on the outside of the exam room. While the MRI scanner is running, you will hear several loud knocking sounds. We will provide you with earphones for listening to music during the exam to make you more comfortable.
Most MRI scans take between 30 – 45 minutes.
If you believe you are claustrophobic, please inform your physician or our staff prior to your exam and we can arrange to provide you with a mild sedative. We will ask that you arrange to have someone drive you home after the exam.
When and how will you receive your results?
Following your MRI study, one of our Radiologists will interpret your exam and provide a report to your physician. Your physician will call you when the report has been received and will discuss the results with you.
