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.
