Shoulder-MRI using conventional TSE sequences often exhibit artifacts resulting in non-diagnostic images due to involuntary patient movement. A recent developed multishot T2-weighted sequence based on rotating rectangular read-out of k-space data (BLADE) is supposed to reduce motion artifacts. This study compared BLADE to a conventional fat-saturated TSE sequence used in musculoskeletal radiology, revealing significant reduction of motion artifacts, improvement of image quality, depiction of anatomical detail and improved diagnostic confidence of anterior labral lesions. Thus BLADE provides a promising alternative for examination of young, critically ill or claustrophobic patients, who express a higher probability for motion artifacts.
