In this work, we evaluate the efficacy of Spectral-Heterogeneity-Adaptive Radiofrequency Pulses (SHARP)-based partial fat saturation for improving meniscal pathology conspicuity at 3T and 7T. Under the guidelines of an IRB, 11 subjects with knee meniscal pathology detected on a previous 3T MRI were imaged at 3T and 7T using six different turbo spin-echo–based MRI imaging options that included SHARP. Two fellowship-trained musculoskeletal radiologists evaluated meniscal pathology conspicuity and selected the top three preferred options for each case. SHARP improved conspicuity of meniscal pathology at 3T and 7T and was within top three preferred options for the highest number of times.
