What is an MRI?


Magnetic Resonance Imaging, or MRI, is a non-invasive imaging technology that uses powerful magnets in order to create very detailed 3-D images of body tissues. These powerful magnets cause the alignment of protons within the body tissue, and then a radio frequency current moves the protons out of this alignment. When the radio frequency current stops, MRI sensors detect the alignment changes as the protons realign themselves.

Contrast agents may be given via an IV in order to increase the proton alignment in the magnetic field. The quicker the protons align the brighter the final image appears.



What is an MRI scan used for?


An MRI can be used for:

Soft tissues: 
MRIs are good at building images of the soft tissues — they provide clearer images than X-rays or CT scans provide for tendons, muscles, nerves, ligaments, the spinal cord, and the brain.

Brain scans:
An MRI distinguishes between grey and white brain matter and therefore is often used to diagnose tumors and aneurysms. They are better than CT scans at diagnosing brain atrophy or small strokes.

Frequent or repeat scans:
Different than CT scans or X-rays, MRIs do not use radiation to build images. Thus, they are commonly the type of scan utilized to perform repeat imaging.

Frequently Asked Questions


Does an MRI Scan Hurt?

No, an MRI scan should not hurt. You will need to remove any metal jewelry and leave your cell phone outside of the scanning room before you can get into the MRI scanner. This is done to prevent any injuries that the powerful magnets could cause. Speak with your ordering physician as well as your MRI technician about any concerns you may have before your scan. The team at Innovative Medical Imaging is also happy to walk you through any questions you have before your MRI scan in Twin Falls.


How Long will My MRI Scan Take?

The duration of your MRI scan will depend on a few different factors.

  • The complexity of the scan's purpose
  • The area being scanned
  • Whether or not contrast is being used

On average, brain and spine scans can take about 45 minutes. A cardiac MRI scan will typically take a bit longer because of the heart's natural movement. It's important to remember that these estimates are just a generalization, and the length of your scan will vary based on your exact situation. When you schedule an MRI in Twin Falls at Innovative Medical Imaging, a member of our scheduling team will contact you to schedule your appointment. They will tell you during the scheduling call how long the estimated test will take so you can plan accordingly.
