Veterinary MRI with John Posh, RT (R)(MR)

RACE Program Agenda

Requirements for Course Enrollment and Completion:

Veterinarians and licensed veterinary technicians will enroll for the program through the AAVR website ( The cost for the program is $1,500, and participants may enroll at any time. There is no timeline to finish the course, and students may work at their own pace.

This online course will feature 13 videos created by John Posh, RT (R)(MR) for students to watch, followed by a 10- to 15-question exam (30-minute max given to finish) at the completion of each video. In order to advance to the next video, students must pass an online test with a score of 70% or higher, per RACE standards, for each video. They must complete and pass all 13 exams in order to receive CE credit for this course. Based on the length of videos and time allotted for taking each exam, this course takes approximately 16 hours maximum to complete. (Applied for 14.5 hours due to the rounding up or down of hours to meet RACE minimum CE credit time requirements.)

Technical Portion:


The technical portion of this course requires each applicant to independently perform and submit MRI studies.All MRI studies submitted must be complete (see AAVR MRI guidelines).  All studies must be done independently by the applicant and obtained after starting the online course. Studies will be assessed by a boarded specialist selected by the AAVR for study completeness, image positioning and proper sequence technique. Assessment of each series will be given an overall pass/ no pass and each applicant must receive a pass for the study to count towards the AAVR technical requirements.  To arrange for the image sending procedures, please contact us at This email address is being protected from spambots.
