Abstract:
Objective To investigate the effect of MRI in the evaluation of extra-capsular extension (ECE)of prostate cancer.Methods Preoperative MR imaging findings were correlated with histologic findings in 29 patients underwent radical prostatectomy regarding the ECE,the diagnostic accuracy was evaluated retrospectively.Results Histopathological results showed capsular penetration in 9 of 29 patients (31.0%).The sensitivity,specificity,positive predictive value,and negative predictive value of MR imaging were 3/9,90%(18/20),3/5 and 75%(18/24),respectively.The overall accuracy was 72.4% (21/29).Conclusion MR imaging has relatively low sensitivity and high specificity for diagnosis of ECE of prostate cancer,the accuracy is somewhat limited.
