BACKGROUND
The purpose of this study was to compare the diagnostic efficiency of a thyroid ultrasound computer-aided diagnosis (CAD) system with that of 1 radiologist.
METHODS
This study retrospectively reviewed 342 surgically resected thyroid nodules from July 2013 to December 2013 at our center. The nodules were assessed on typical ultrasound images using the CAD system and reviewed by 1 experienced radiologist. The radiologist stratified the risk of malignancy using the Thyroid Imaging Reporting and Data Systems (TIRADS) and the American Thyroid Association (ATA) guidelines.
RESULTS
The radiologist, using TI-RADS and ATA guidelines, performed better than the CAD system (P < .01). The sensitivity of the CAD system was similar to that of an experienced radiologist (P > .05; P < .01; and P > .05). However, we found that the CAD system had lower specificity (P < .01).
CONCLUSION
The sensitivity of a thyroid ultrasound CAD system in differentiating nodules was similar to that of an experienced radiologist. However, the CAD system had lower specificity.
背景
本研究旨在比较甲状腺超声计算机辅助诊断（CAD）系统与一名放射科医生的诊断效率。
方法
本研究回顾性分析了2013年7月至2013年12月在本中心手术切除的342个甲状腺结节。使用CAD系统在典型超声图像上对结节进行评估，并由一名经验丰富的放射科医生进行复查。放射科医生根据甲状腺影像报告和数据系统（TIRADS）及美国甲状腺协会（ATA）指南对恶性风险进行分层。
结果
使用TI-RADS和ATA指南时，放射科医生的表现优于CAD系统（P <.01）。CAD系统的敏感性与经验丰富的放射科医生相似（P >.05；P <.01；P >.05）。然而，我们发现CAD系统的特异性较低（P <.01）。
结论
甲状腺超声CAD系统在鉴别结节方面的敏感性与经验丰富的放射科医生相似。然而，CAD系统的特异性较低。
