超声(US)是甲状腺结节的主要诊断工具，但其准确性依赖于操作者。它不仅被放射科医生广泛使用，而且被具有不同水平经验的医生广泛使用。本研究的目的是探讨超声与计算机辅助诊断(CAD)在甲状腺结节诊断中是否对医生有辅助作用。451个甲状腺结节经手术后细针吸取细胞学检查。其中300例(66.5%)被诊断为恶性肿瘤。有美国经验不足1年(无经验，n = 10)或超过5年(有经验，n = 3)的医生在接受或不接受辅助检查的情况下检查甲状腺结节的超声图像。冠心病诊断能力与有经验组相当，优于无经验组。与肿瘤大小无关，常规PTC组CAD的AUC值高于FTC组和滤泡型PTC组(0.925比0.499)。CAD辅助显著改善了无经验组的诊断性能，但在有经验的组中并非如此。综上所述，该CAD系统对常规PTC的诊断具有良好的性能。CAD辅助改善了美国经验较少的医生的诊断能力，特别是在传统PTC的诊断方面。
Ultrasonography (US) is the primary diagnostic tool for thyroid nodules, while the accuracy is operator-dependent. It is widely used not only by radiologists but also by physicians with different levels of experience. The aim of this study was to investigate whether US with computer-aided diagnosis (CAD) has assisting roles to physicians in the diagnosis of thyroid nodules. 451 thyroid nodules evaluated by fine-needle aspiration cytology following surgery were included. 300 (66.5%) of them were diagnosed as malignancy. Physicians with US experience less than 1 year (inexperienced, n = 10), or more than 5 years (experienced, n = 3) reviewed the US images of thyroid nodules with or without CAD assistance. The diagnostic performance of CAD was comparable to that of the experienced group, and better than those of the inexperienced group. The AUC of the CAD for conventional PTC was higher than that for FTC and follicular variant PTC (0.925 vs. 0.499), independent of tumor size. CAD assistance significantly improved diagnostic performance in the inexperienced group, but not in the experienced groups. In conclusion, the CAD system showed good performance in the diagnosis of conventional PTC. CAD assistance improved the diagnostic performance of less experienced physicians in US, especially in diagnosis of conventional PTC.
