目的：确定直肠内磁共振 (MR) 成像结果在检测前列腺癌囊外扩展 (ECE) 方面的预测价值是否会受到读者的亚专业经验的显着影响。 材料和方法：在这项队列研究中，连续 344 名活检证实的前列腺癌患者接受了直肠内 MR 成像，然后进行了手术。将 MR 成像报告中描述的 ECE 可能性与临床预测变量进行比较。 ECE 根据手术切除标本的最终病理报告确定。 MR 图像的读者分为泌尿生殖 MR 成像放射科医生 (n = 4) 和全身 MR 成像放射科医生 (n = 6)。对于数据分析，使用了 Wilcoxon 秩和和 chi(2) 检验、受试者工作特征 (ROC) 曲线以及单变量和多变量逻辑回归分析。与P的区别
PURPOSE: To determine whether predictive value of endorectal magnetic resonance (MR) imaging findings in detection of prostate cancer extracapsular extension (ECE) is significantly affected by the reader's subspecialty experience.MATERIALS AND METHODS: In this cohort study, 344 consecutive patients with biopsy-proved prostate cancer underwent endorectal MR imaging followed by surgery. Likelihood of ECE described in MR imaging reports was compared with clinical predictor variables. ECE was determined from the final pathologic report on specimens resected at surgery. Readers of MR images were classified into genitourinary MR imaging radiologists (n = 4) and general body MR imaging radiologists (n = 6). For data analysis, Wilcoxon rank sum and chi(2) tests, as well as receiver operating characteristic (ROC) curves and univariate and multivariate logistic regression analyses, were used.
