Direct-coronal diffusion-weighted whole body imaging with background body signal suppression using single-shot turbo spin-echo (TSE-DWIBS) with b-values of 400, 600, 800, and 1000 mm2/s, and DWIBS using echo-planner imaging (EPI-DWIBS) with b-value of 1000mm2/s were obtained using 3T MR scanner in 5 healthy volunteers. We investigated optimal b-value of TSE-DWIBS and compared image distortions, contrast, signal-to-noise ratio (SNR), and artifacts between TSE-DWIBS and EPI-DWIBS. Image contrast and SNR of TSE-DWIBS with b-value of 800 mm2/s were equivalent to those of EPI-DWIBS with b-value of 1000 mm2/s. TSE-DWIBS had less image distortions and artifacts than EPI-DWIBS. Direct-coronal TSE-DWIBS using 3T MRI can be applied for clinical cases.
