The diagnostic value of PI-RADS score based on multi-parameter magnetic resonance imaging in preoperative staging of prostate cancer
Objective To investigate the diagnostic value of multi-parameter magnetic resonance(mp-MRI)based prostate imag-ing reporting and data system(PI-RADS)score in the preoperative stage of prostate cancer.Methods The 102 patients with suspected prostate cancer admitted to the hospital from March 2021 to April 2022 underwent mp-MRI,PI-RADS score was performed on mp-MRI images,and surgical pathology or needle biopsy was performed in parallel.The results of surgical pathology or needle biopsy were regarded as the"gold standard".To analyse the diagnostic efficacy of PI-RADS score of mp-MRI on prostate cancer and preoperative stage.Results 73 of 102 patients with suspected prostate cancer were confirmed by surgical pathology or needle biopsy,accounting for 71.57%,among these,12 cases were in stage A,of the 24 patients in stage B,of the 29 patients in stage C,8 cases in stage D.Accord-ing to the"gold standard"of surgical pathology or needle biopsy examination,the PI-RADS score of mp-MRI had a diagnostic sensitiv-ity of 95.89%(70/73),specificity of 96.55%(28/29)and accuracy of 96.08%(98/102).Moreover,the rate of PI-RADS score for clinical stage of prostate cancer was 93.15%(68/73),It showed excellent agreement with surgical pathology or needle biopsy results(Kappa value=0.901).Conclusion PI-RADS score based on mp-MRI has high diagnostic value for preoperative diagnosis and staging of prostate cancer and is worthy of clinical application.
