In patients with metallic hip implants, distortions and other artifacts relating to the echo-planar imaging acquisition may render prostate DWI non-diagnostic. Reduced field-of-view (rFOV) acquisition, using parallel transmission and focused excitation, is a novel DWI approach that reduces distortions and improves images quality. This article presents images from both standard and rFOV DWI acquisitions in two prostate cancer patients with hip implants, showing the impact of rFOV DWI for improving tumor localization. The findings have implications for the potential application of MRI for guiding targeted biopsy and planning focal therapy in the growing population of patients with hip implants.
