旨在评估交互式专门培训对放射科研究员通过 MRI 评估前列腺癌准确性的影响。11 名放射科研究员在不了解临床和病理数据的情况下，独立解释术前前列腺 MRI 研究，对肿瘤在外周和移行区以及囊外扩展的可能性进行评分。每个研究员在专门培训之前解释了 15 项研究（以提供基线解释准确性），在参加教学讲座后解释了 200 项研究（10 次/周）。放射科医生专家主持每周一次的互动教程，将研究员的解释与病理肿瘤图进行比较。为了评估解释准确性，以病理结果为参考标准，进行受试者操作特征（ROC）分析。在识别周围区肿瘤时，研究员的平均ROC曲线下面积（AUC）从0.52增加到0.66（教学讲座后；p < 0.0001）并保持在0.66（培训结束；p < 0.0001）；在过渡区，他们的平均 AUC 从 0.49 增加到 0.64（教学讲座后；p = 0.01），再增加到 0.68（训练结束；p = 0.001）。在检测包膜外扩展时，他们的平均 AUC 从 0.50 增加到 0.67（教学讲座后；p = 0.003）和 0.81（训练结束；p < 0.0001）。交互式专门训练显着提高了肿瘤定位的准确性，特别是在前列腺 MRI 上检测包膜外扩展方面。
To assess the effect of interactive dedicated training on radiology fellows' accuracy in assessing prostate cancer on MRI.Eleven radiology fellows, blinded to clinical and pathological data, independently interpreted preoperative prostate MRI studies, scoring the likelihood of tumour in the peripheral and transition zones and extracapsular extension. Each fellow interpreted 15 studies before dedicated training (to supply baseline interpretation accuracy) and 200 studies (10/week) after attending didactic lectures. Expert radiologists led weekly interactive tutorials comparing fellows' interpretations to pathological tumour maps. To assess interpretation accuracy, receiver operating characteristic (ROC) analysis was conducted, using pathological findings as the reference standard.In identifying peripheral zone tumour, fellows' average area under the ROC curve (AUC) increased from 0.52 to 0.66 (after didactic lectures; p < 0.0001) and remained at 0.66 (end of training; p < 0.0001); in the transition zone, their average AUC increased from 0.49 to 0.64 (after didactic lectures; p = 0.01) and to 0.68 (end of training; p = 0.001). In detecting extracapsular extension, their average AUC increased from 0.50 to 0.67 (after didactic lectures; p = 0.003) and to 0.81 (end of training; p < 0.0001).Interactive dedicated training significantly improved accuracy in tumour localization and especially in detecting extracapsular extension on prostate MRI.
