This page is for OHSU's MRI technologists and physicians. It outlines all sequences and protocols currently applied in our MRI section.  Our radiologists work closely with OHSU MRI technologists in the art of creating optimal images using current technology. Protocols listed have been reviewed and approved by a radiologist.

Body imaging protocols currently applied in our MRI section.  Radiologists work closely with OHSU MRI techs in the art of creating optimal images from current technology. Dr. Alice Fung has approved the protocols below.  All body protocols for pediatric patients are under Pediatric Protocols.

Technologist Tips

  • Page the Body Radiologist to check images if you have any questions regarding the exam.
  • For all Pelvic MRI studies except the Bladder Protocol or the MR Urogram: Please have the patient void their bladder prior to exam to improve image quality.

MSK protocols currently applied in our MRI section.  Radiologists work closely with OHSU MRI techs in the art of creating optimal images from current technology. Dr. Barry Hansford has approved the protocols below.  All MSK protocols for pediatric patients are under Pediatric Protocols.

ANY INFECTION/OSTEO CASE REGARDLESS OF BODY PART:

  • If infection/osteo is a diagnostic consideration, please run 3 PLANES T1 without FS. (Infection cases aren't always ordered with contrast).
  • If for infection/osteo and is ordered with GAD, always run 3 PLANES T1 without FS PRE contrast.  (Infection cases aren't always ordered with contrast).
  • If GAD is administered, all the post contrast imaging must be fat sat, there is zero value in non fat sat post contrast imaging for MSK. 
  • DIFFICULT PATIENTS: Start exams with AX T1 non-fat sat sequences in case the exam is terminated early for difficult patients.

IF HARDWARE IS PRESENT IN THE AREA OF INTEREST:

  • Try to assess beforehand whether or not hardware will interfere with protocol. Hardware doesn't necessarily mean you have to change the protocol. If available, Check an X-ray. You may be able to decide before hand (discuss with radiologist if needed).
  • Try a fat-sat mid-TE sequence- is there too much susceptibility artifact and/or inhomogeneous fat suppression? (discuss with radiologist if needed)
  • If the protocol needs to be modified: 
    • Perform on 1.5T
    • Increase Bandwidth if possible
    • Run non-fat-sat mid-TE sequences or STIR instead of fat-sat mid-TE
    • If post-contrast, do non-fat-sat T1 instead of fat-sat T1

Pediatric imaging protocols currently applied in our MRI section.  Radiologists work closely with OHSU MRI techs in the art of creating optimal images from current technology. Dr. Andrew Phelps has approved the protocols below.  The pediatric radiologists will usually protocol specific sequences they need in RIS. If not, follow the adult protocol, but make changes to the slice, gap, and FOV as needed.

Sedated Children and Checking Images

  • As of 5/13/2021 for sedated children only: Pediatric Radiologist must check images before giving contrast and prior to letting the patient off the table unless otherwise stated in the protocol. No need to have images checked on non-sedated children unless there is a question or a concern.
  • Neuro exams do not need to be checked unless there is a question or a concern.

Body, MSK & Chest

  • Upper extremities from finger to shoulder: use adult MSK protocols with FOV/Slice/Gap adjustments for patient size.
  • Lower extremities NOT listed below: use adult protocols with FOV/Slice/Gap adjustments for patient size.
  • Please run AX T1 FS PRE GAD for all MSK WWO exams.

Important notes -updated 12/2/19

  • Do NOT change any study parameters to reduce scan times, especially if it states in multiple places not to change parameters. 
  • Some exams are NO READ. Be sure to select the appropriate box in EPIC if the exam is not to be read by a radiologist.
  • Do NOT add a screen capture note to the study, as this will capture PHI on the images which will negate the anonymity requirement for the research study.
