The usefulness of short TR DWI in prostate has been reported. However, care should be taken when setting TR as DWI with shorter TR suffers from low SNR. It would be beneficial to generate an additional DWI with shorter TR (e.g. 1000ms) from DWIs with two different TR (e.g. conventional [long] and short TR such as 6000 and 2000ms). The synthetic DWI at b = 1000 s/mm² (DWI₁₀₀₀) with shorter TR of 1000ms calculated from DWIs with TR of 6000 and 2000ms had a tendency to show better diffusion contrast compared to the real-acquired DWI₁₀₀₀ with long TR of 6000ms.
