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.
