: Although images of the sacro-iliac joint of seventeen of the twenty-seven study subjects were partially already reported on in the study of Jans et al. [], we emphasize that in the same patients, fully different body regions were scanned and a different algorithm was used. There is no overlap here as no part of this study has ever been reported.[1] Jans L, Chen M, Elewaut D, et al.
