To compare the simultaneous acquisition of multiple slices (SMS) with turbo spin echo (TSE) sequences to routine TSE sequences in musculoskeletal (MSK) imaging. 10 healthy volunteers and 8 patients with knee joint disorders were examined in two sequences at 3T. The basic acquisition parameters for two sequences were similar. Slice accelerated factor was 2 and FOV shift factor was 2 for SMS sequences. Signal-to-noise ratio (SNR) and contrast-to-noise ratio were calculated in volunteers, respectively. Two radiologists visually evaluated the images of patients double blindly. SMS TSE requires less scan time and offers higher SNR, especially for large coverage MSK examination.
