Representative image quality of 3D DP-TSE compared with that of conventional 2D SS-DWEPI from a healthy subject. (A to C) DWI of b = 30 mm2/s, DWI of b = 300 mm2/s and ADC map, respectively, acquired using DP-TSE with resolution of 0.6 × 0.6 × 2.0 mm3. (D to F) DWI of b = 50 mm2/s, DWI of b = 300 mm2/s and ADC map, respectively, acquired using SS-DWEPI with resolution of 1.2 × 1.2 × 2.0 mm3. Note that blurring, distortion and artifacts were present in the SS-DWEPI images compared with their counterparts from DP-TSE. Also note that SS-DWEPI images had higher T2 decay due to the longer required TE than that of the proposed DP-TSE.
