Magnetic Resonance Imaging (MRI)

VI.    Magnetic Resonance Imaging (MRI)

A.         Overview

  • MRI uses strong magnetic fields and radiowaves, not x-rays, to create high-contrast three-dimensional tomographic images (“slices”) of any part of the human anatomy. 
  • Intravenous gadolinium-based contrast media may be given to enhance normal anatomy and delineate pathology. 
  • MRI may be conducted safely in most volunteers, including children, and pregnant women and may be repeated without risk.
  • Imaging in patients with implanted devices (e.g., pacemaker) is generally contraindicated.

B.        Facilities, Technical Capabilities & Limitations

  • There are seven MR scanners available for human research.
  • All scanners are high-field (1.5T or 3.0T), superconducting systems.    
  • All units produce high-quality digital images.
  • Images are viewable and archived on the Enterprise-wide McKesson PACS; CDs/DVDs can be created as needed.
  • Radiology reports are viewable through SCM/AEHR and can be printed as needed.

 E.        Costs

  • Please discuss project and all applicable costs with Radiology Senior Research Coordinator prior to IRB and/or grant submission or renewal. 
  • Radiology costs include the technologist’s time to prepare and image the patient/human research subject according to protocol, process the image data, and archive the images to a CD/DVD if required by the investigator or study sponsor. 
  • Supply costs might be incurred, e.g., contrast media.
  • Professional services by radiology physicians and/or medical physicists are negotiable.
