Synopsis

This study aims to investigate the value of quantitative relaxation time derived from synthetic MRI (SyMRI) in the diagnosis and grading of prostate cancer (PCa). The results of this study showed that the diagnostic efficiencies of SyMRI in distinguishing PCa from most benign prostate lesions and different Gleason grades of PCa were similar to that of DWI, and the combined index of SyMRI and DWI can obtain higher diagnostic efficiencies. In addition, SyMRI has the advantages of short scanning time, unified parameters and simple operation, so it has a good prospect of clinical application.
