title: Absence of chemical shift artifact on coronal T1-weighted MR images: an undescribed finding seen in osteochondral injuries of the knee in 12 patients.
abstract: OBJECTIVE
  The purpose of this article is to report a previously undescribed MR imaging finding that is associated with osteochondral injuries of the knee.
  
  
  CONCLUSIONS
  In adult patients, segmental absence of chemical shift artifact in the subchondral femoral condyles on T1-weighted MR images is associated with osteochondral fractures.
