A 3D TSE (SPACE) sequence using SPARSE-SENSE
acceleration was optimized and compared to conventional
multiplanar 2D TSE sequences in 21 patients for the
evaluation of internal derangement of the knee. The
optimized SPACE sequence demonstrated no statistically
significant difference in sensitivity, specificity, or
accuracy for the detection of meniscal or ligament tears
when compared with the 2D TSE sequences using
arthroscopy as the gold standard. If substantiated in
larger clinical studies, this could lead to significant
shortening of exam time, potentially enlarging the
indication and utilization of knee MR as well as
decreasing its cost.
