SIJ<\/jats:styled-content>\u2010MRI<\/jats:styled-content> exams were retrospectively analyzed by two musculoskeletal radiologists. Patients were separated into BME<\/jats:styled-content> group and non\u2010BME<\/jats:styled-content> group according to whether there was BME<\/jats:styled-content> of SIJ<\/jats:styled-content> demonstrated as high signal intensity on MR<\/jats:styled-content> short tau inversion recovery sequences beneath the SIJ<\/jats:styled-content> articular surface.

Ilium side BME<\/jats:styled-content> demonstrated with OCI<\/jats:styled-content> was centered at the ventral\u2010cartilaginous joint part and had a trend of extending to bone marrow beneath the arcuate line in a continuous distribution pattern. There was a trend that OCI<\/jats:styled-content> patients with BME<\/jats:styled-content> demonstrated on MRI<\/jats:styled-content> were younger (P<\/jats:italic> = 0.054, Student's t<\/jats:italic>\u2010test) and with shorter pain duration (P<\/jats:italic> = 0.091, Student's t<\/jats:italic>\u2010test) than OCI<\/jats:styled-content> patients without BME<\/jats:styled-content>, but the differences did not reaching statistical significance.
