为了比较基于弥散加权成像（DWI）的非增强简化磁共振成像（MRI）和简化增强后MRI对乳腺癌的可检测性，研究人群包括2016年12月至2017年3月在临床环境中接受乳腺MRI的87例患者。所有乳腺MRI均使用1.5 T MRI扫描仪和16通道乳腺射频线圈进行。由两名放射科医师独立评估基于DWI（AP 1）和增强MRI（AP 2）的简化方案。计算灵敏度和特异性。采用受试者工作特征分析方法，比较AP1和AP2的曲线下面积（AUC）。研究对象包括87例乳腺癌患者，共89个病灶
To compare the detectability of unenhanced abbreviated magnetic resonance imaging (MRI) based on diffusion-weighted imaging (DWI) and abbreviated postcontrast MRI for breast cancer.The study population consisted of 87 patients undergoing breast MRI between December 2016 and March 2017 in a clinical setting. All breast MRIs were performed using a 1.5-T MRI scanner with a 16-channel breast radiofrequency coil. The abbreviated protocols based on DWI (AP1) and postcontrast MRI (AP2) were assessed independently by two radiologists. Sensitivity and specificity were calculated. Receiver operating characteristic analysis was performed and the areas under the curves (AUCs) were compared between AP1 and AP2.The study included 87 patients with 89 breast cancer lesions
