Frequently Asked Questions About MRI
1. Is MRI superior to other imaging techniques (CT-scan, x-ray, etc.)?
Often, yes. MR images can be made from many different angles to give a better view of the tissues in question. MRI can also provide a level of detail that is often difficult to achieve with x-rays or other imaging systems. Because it captures relatively subtle difference in shape and appearance, an MRI image can help your doctor determine which tissues are healthy and which are not.
Best of all, you will not be exposed to any radiation when you receive an MRI scan.
2. What does “High Field” mean?
When you are in a MRI scanner your body puts off a signal that is picked up by our imaging coil. Generally speaking, the higher the field strength of the magnet, the higher the signal received by the imaging coil. Magnets are categorized by their field strength. Magnets of 1.0 Tesla or higher are considered high field magnets. Magnets between .5 Tesla and 1.0 Tesla are considered mid-field magnets. Magnets below .5 Tesla are considered low field magnets. In partnership with MRI Mobile, we employ a GE 1.5T “High Definition” MRI system.
3. What if I am claustrophobic?
If you know this in advance of the exam, please discuss this with your primary care provider. He or she can prescribe an oral medication to help you relax. Be sure to follow prescribing instructions about when to take your prescription. Even if you are claustrophobic, our technologist will work with you to help you feel at ease throughout the exam.
