Relationship between radiologist training level and radiation exposure for therapeutic hip injections.

Objective: The aim of this study was to determine the relationship between the level of training of the performing radiologist and patient radiation exposure, as measured by fluoroscopy time (FT) and dose area product (DAP), during fluoroscopic guided hip injections.

Materials And Methods: This IRB-approved retrospective review of our institutional radiology report database identified all fluoroscopic guided hip injections performed between August 1st, 2012 and May 30th, 2015. Performing radiologists were divided into groups based on their level of training at the time of the procedure: first-year residents (R1), second-year residents (R2), third-year residents (R3), fourth-year residents (R4), staff fellowship trained musculoskeletal radiologists, and non-musculoskeletal radiologists.
