Synthetic DWI at b = 1000 s/mm2 (DWI1000) with shorter TR of 1000ms had a tendency to
show better contrast than conventional DWI1000 with long TR of
6000ms.
Figure 2. Prostate cancer in transitional zone. Cancer lesion
is shown as a homogeneous hypointense lesion with mass effect on T2WI (arrow). synDWI1000
with shorter TR provided better contrast than DWI1000 with long TR,
whereas noise in synDWI1000 with TR of 500ms become more visible.

synDWI1000 with shorter TR of 1000ms and DWI1000 with
long TR of 6000ms in three patients.
