“…We have read with interest the manuscript entitled ''Does Immobilization Post Injection Reduce Contrast Extravasation in MR Arthrography of the Shoulder?'' by Muylaert et al 1 which is one of few articles assessing measures to reduce iatrogenic extravasation from theglenohumeral joint following arthrography prior to MR. The authors should be commended for contributing to this currently sparse area of research, particularly in their efforts to test for a correlation between extravasation and image quality.…”
