The MRI findings were categorized using three bpMRI-based scorings, in all of them the diffusion-weighted imaging (DWI) was the dominant sequence for peripheral zone (PZ) and T2-weighed imaging (T2WI) was the dominant sequence for transition zone (TZ). We also used the Prostate Imaging Reporting and Data System version (PI-RADS) v2.1 to evaluate each lesion. For each scoring, we calculated the sensitivity, specificity, negative predictive value (NPV), positive predictive value (PPV), and area under the receiver operating characteristic (ROC) curves (AUC).</div></div><div><h3>Results</h3><div>The calculated AUC for three bpMRI-based scorings were 83.2% (95% CI 78.8%–87.6%), 85.0% (95% CI 80.8%–89.3%), 82.9% (95% CI 78.4%–87.5%), and 86.0% (95% CI 81.8%–90.1%), respectively. Scoring 2 exhibited significantly superior performance than scoring 1 (<em>P</em> = 0.01) and scoring 3 (<em>P</em> &lt; 0.001). Moreover, the accuracy of scoring 2 was not decreased significantly as compared to PI-RADS v2.1 (<em>P</em> = 0.05). There was no significant difference between 3 bpMRI-based scorings and with PI-RADS in TZ. However, although scoring 2 yielded the highest AUC, it was still notably inferior to PI-RADS (<em>P</em> = 0.02).</div></div><div><h3>Conclusion</h3><div>All three bpMRI-based scorings demonstrated favorite diagnostic accuracy, and scoring 2 performed significantly better than the other two bpMRI-based scorings. Notably, scoring 2 was not significantly inferior to the full-sequence PI-RADS v2.1 in terms of sensitivity and specificity.</div></div>","PeriodicalId":20845,"journal":{"name":"Prostate International","volume":"12 4","pages":"Pages 201-206"},"PeriodicalIF":2.7,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142189100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
