Higher SNR and more clear anatomical
structure of APTw images in prostate was acquired with the
optimal scan parameters: the number of slices
of 7,
voxel
of 2×2 mm2, the
echo train length of 100, small FOV of 130×100×49mm3,
fold-over suppression of rest, SENSE of 1.1, phase
encoding direction of AP.
