OBJECTIVE
To analyze the clinical value of high b-value 3.0 T biparametric magnetic resonance with the Simplified Prostate Image Reporting and Data System (S-PI-RADS) in biopsy-naïve men.
METHODS
A retrospective analysis of the data of 224 patients who underwent prostate biopsy (cognitive fusion targeted biopsy combined with systematic biopsy) after a high b-value 3.0 T magnetic resonance examination at Haikou Hospital from July 2018 to July 2020 was performed. Two radiologists performed multi-parameter magnetic resonance imaging (mp-MRI) with the prostate imaging report and data system version 2 (PI-RADS v2) and biparametric magnetic resonance imaging (bp-MRI) with the simplified prostate image reporting and data system (S-PI-RADS). The detection efficacy of the two regimens was evaluated by classifying prostate cancer (PCa) and clinically significant prostate cancer (csPCa) according to pathology, and the statistical significance of the differences between the two regimens was determined by Z-test.
RESULTS
The area under the receiver operating curve (AUC) values of mp-MRI based on PI-RADS v2 and bp-MRI based on S-PI-RADS to detect PCa were 0.905 and 0.892, respectively, while the AUC values for the detection of csPCa were 0.919 and 0.906, respectively. There was no statistically significant difference between the two tests (Z values were 0.909 and 1.145, p > 0.05).
CONCLUSION
There was no significant difference in the detection efficacy of high b-value bp-MRI based on the S-PI-RADS score for prostate cancer and clinically significant prostate cancer compared with the standard PI-RADS v2 score with mp-MRI protocols, which can be applied clinically.
目的
分析在未经活检的男性中，高 b 值 3.0T 双参数磁共振成像联合简化前列腺影像报告与数据系统（S-PI-RADS）的临床价值。
方法
回顾性分析 2018 年 7 月至 2020 年 7 月在我院行高 b 值 3.0T 磁共振检查后行前列腺穿刺活检（认知融合靶向活检联合系统活检）的 224 例患者的临床资料。两名放射科医生分别采用前列腺影像报告和数据系统第 2 版（PI-RADS v2）多参数磁共振成像（mp-MRI）和简化前列腺影像报告和数据系统（S-PI-RADS）双参数磁共振成像（bp-MRI）对患者进行检查。根据病理结果将前列腺癌（PCa）和临床显著前列腺癌（csPCa）进行分类，评估两种方案的检测效能，采用 Z 检验比较两种方案的差异是否具有统计学意义。
结果
PI-RADS v2 评分 mp-MRI 检测 PCa 的受试者工作特征曲线（ROC）下面积（AUC）值为 0.905，S-PI-RADS 评分 bp-MRI 检测 PCa 的 AUC 值为 0.892，PI-RADS v2 评分 mp-MRI 检测 csPCa 的 AUC 值为 0.919，S-PI-RADS 评分 bp-MRI 检测 csPCa 的 AUC 值为 0.906。两种检查方法的 AUC 值差异均无统计学意义（Z 值分别为 0.909、1.145，p>0.05）。
结论
S-PI-RADS 评分 bp-MRI 检测前列腺癌和临床显著前列腺癌的效能与标准 PI-RADS v2 评分 mp-MRI 方案比较差异无统计学意义，可在临床应用。
