Abstract:
Objective To explore the methods of improving diagnosis correctness between the patients with prostate cancer and benign prostatic hyperplasia.Methods Totally 87 patients with benign prostatic hyperplasia or prostate cancer which confirmed by MRI and prostate biopsy for the PSA significantly increased in our hospital from July 2013 to March 2016 were collected.By using the three methods of the PI-RADS V2 score,the T2WI+DWI/ADC+DCE-MRI+MRS and PI-RADS V2 score+MRS to diagnose,and comparing with the pathology results,the diagnostic consistency of the two physicians were analyzed.The sensitivity,accuracy and specificity of three ways were compared,and the correlation between PI-RADS V2 score and Gleason score were calculated.Results The diagnostic consistency of the two physicians:PI-RADS V2 score,K=0.951;T2WI+DWI/ADC+DCE-MRI+MRS score,K=0.838;PI-RADS V2+MRSI score,K=0.937.The correlation between PI-RADS V2 score and Gleason score,r=0.871,P=0.001 4;diagnostic sensitivity,specificity and accuracy of PI-RADS V2 score were 77.3％,74.4％,75.9％;diagnostic sensitivity,specificity and accuracy of T2WI+DWI/ADC+DCE-MRI+MRS were 88.6％,76.7％,82.8％;diagnostic sensitivity,specificity and accuracy of PI-RADS V2+MRSI score were 86.4％,81.4％,83.9％,respectively.Conclusion Compared with the traditional diagnostic methods,the combination of new prostate report and data system and MRSI can improve the diagnostic accuracy of prostate cancer and benign prostatic hyperplasia.The PI-RADS V2 score is more objective and accurate in the description of the lesion,but the low signal of benign hyperplastic nodules in transitional zone should be dialogued carefully through a variety of image parameters.
