A Cube 3D-FSE sequence was performed with and without compressed sensing (CS) twice on the knees of 10 asymptomatic volunteers to assess signal-to-noise- ratio (SNR) and once on the knees of 25 symptomatic patients to assess diagnostic performance for detecting knee joint pathology. CS k-space acceleration provided a 30% reduction in scan time without a corresponding decrease in SNR. The use of CS resulted in mild increased image blurring which did not influence diagnostic performance with near perfect to perfect agreement between Cube and Cube-CS for detecting knee joint pathology.
