Si Y, et al. - Researchers compared the diagnostic performance of monoexponential DWI and diffusion kurtosis imaging (DKI) for the detection of prostate cancer (PCa) through a systematic review and meta-analysis. A systematic literature search was undertaken to find studies evaluating the diagnostic value of monoexponential DWI and DKI for PCa in the same patient cohorts with sufficient data to construct 2 × 2 contingency tables. In the result, they found monoexponential DWI and DKI displayed comparable diagnostic accuracies for PCa. For the diagnosis of PCa, DKI was a potentially helpful method. Therefore, including DKI in a routine clinical assessment of PCa for the moment was not recommend.
