MRI Services at St. Rose Dominican Hospitals in Las Vegas and Henderson, NV

Dignity Health - St. Rose Dominican offers advanced Magnetic Resonance Imaging (MRI) services at our San Martín Campus in Las Vegas and Siena Campus in Henderson, Nevada. MRI scans are painless and provide detailed images of your body's tissues, bones, and organs without using X-rays (ionizing radiation).

 

Reasons for getting an MRI Scan

MRIs help your doctor diagnose and assess diseases and the extent of your injuries. They provide more detailed information — especially about soft tissues, such as blood vessels, ligaments, muscles, and nerves — than ultrasounds, CT scans, or X-rays. 

Doctors use MRIs to understand the causes of:

  • Unexplained pain
  • Bleeding
  • Vision problems
  • Seizures
  • Numbness 
  • Joint, bone, and muscle problems
  • Signs of aneurysm, stroke, or cancer

 

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.
