Reasons for getting an MRI Scan

Getting Scanned in an MRI Machine

A radiologic technician will perform your MRI in a Dignity Health - St. Rose Dominican hospital or radiology clinic. An MRI scan can last from a few minutes to an hour or more.

During the test, you’ll lie on a table inside the MRI scanner. The scanner is shaped either like an open, flattened ring (open) MRI) or a long tube (conventional MRI). You will need to lie as still as possible while the technician takes a series of pictures. You may need a contrast dye to highlight certain systems or body parts, such as arteries and veins. The contrast may be given by injection, by mouth, or with an enema. 

There is no risk of radiation exposure with an MRI. In rare cases, MRI contrast fluid can cause allergic reactions. 


Understanding Your MRI Results

A radiologist will read your MRI and discuss the results with your doctor. MRIs help your health care team diagnose:

  • Tumors, including benign and cancerous masses of the colon, lungs, brain, breast, prostate, and female reproductive organs
