为了避免细针吸取细胞学(FNAC)的滥用和节省学习曲线的时间，台湾台北国立台湾大学工业工程系与台湾国立台湾大学外科合作，开发了一套计算机辅助检测和诊断(CAD)系统，用于从甲状腺超声检查中发现FNAC的可疑病变。本文旨在介绍CAD系统在甲状腺超声检查中的应用，概述CAD系统在甲状腺超声检查中的实际作用。在超声显示结节的明显横轴(横轴)和纵轴后，计算机系统自动计算和显示微钙化、低回声、不均匀和边界不清四个参数。结果通过半月图中的指针显示。FNAC的必要性取决于阳性结果的大小和数量(右侧显示的指针)。该CAD系统具有客观性、易用性等特点。它可能为确定FNAC的必要性提供了一种简便的方法，但我们必须记住的是，这种方法可以减少FNAC的必要性，而不是取代FNAC对甲状腺癌的诊断。(C)2015年，中华台北医学超声学会。这是一篇CC BY-NC-ND许可证下的开放获取文章。
To avoid abuse of fine-needle aspiration cytology (FNAC) and to save the time of a learning curve, a computer-aided detection and diagnosis (CAD) system to detect suspicious lesions for FNAC from thyroid ultrasonography has been developed by the Department of Industrial Engineering, cooperative with the Department of Surgery at the National Taiwan University, Taipei, Taiwan. The purposes of this article are to introduce how to utilize the CAD system in thyroid ultrasonography, and to outline the real role of the CAD system. After marking the apparently transverse (extending across) axis and longitudinal axis of the nodule appearing by ultrasonography, four parameters are calculated and displayed by the computer system automatically, which include microcalcifications, hypoechoic lesion, heterogeneity, and indistinct margin. The results are displayed by the pointers in the semilunar figures. The necessity of FNAC is dependent on the size and numbers of positive findings (pointers displayed in the right side). This CAD system is objective and easy to use. It may supply an easy method to determine the necessity for FNAC, but what we must keep in mind is that this method can reduce the necessity of FNAC, not replace FNAC for the diagnosis of thyroid cancer.
