Early detection of prostate cancer is urgently needed to improve patients survival rate. In recent years, limited studies have been reported to evaluate MR based suspected prostate lesions by utilizing the prostate T2WI features. In fact, bilateral symmetry exists in normal prostate, and as for a developing lesion, asymmetry gradually appear with symmetry breaking down. In this study, texture bilateral symmetry of prostate T2W Images is attempted to screen efficiently the suspected prostate tumor. The result shows a statistical significant difference between cancerous and the control group. The symmetric feature of prostate should be useful for improving prostate cancer screening.
