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.
