DWI is a key component of mp-MRI in prostate and the usefulness of high b-value DWI has been reported. However, the quality might depend on magnetic field strength and scanner performance. It would be beneficial to acquire sufficient diffusion contrast and ADC using standard b-value of 1000 s/mm2 without an additional higher b-value acquisition. We exploited the difference of T1 between cancer and normal to improve contrast. The contrast of T1 enhanced DWI1000 using short TR was better compared to that of DWI1000 with normal long TR but it was less than that of DWI2000 with normal long TR.
