Abstract

Objective: To explore the diagnostic value of the TUIAS (SW_TH01/II) computer-aided diagnosis (CAD) software system for the ultrasound Thyroid Imaging Reporting and Data System (TI-RADS) features in thyroid nodules.

Materials and methods: This retrospective study enrolled patients with thyroid nodules in Shanghai East Hospital between January 2017 and October 2021. The novel CAD software (SW_TH01/II) and three sonographers performed a qualitative analysis of the ultrasound TI-RADS features in aspect ratio, margin irregularity, margin smoothness, calcification, and echogenicity of the thyroid nodules.

Results: A total of 225 patients were enrolled. The accuracy, sensitivity, and specificity of the CAD software in "aspect ratio" were 95.6%, 96.2%, and 95.4%, in "margin irregularity" were 90.7%, 90.5%, and 90.9%, in "margin smoothness" were 85.8%, 88.5%, and 83.0%, in "calcification" were 83.6%, 81.7%, and 82.0%, in "homogeneity" were 88.9%, 90.6%, and 82.2%, in "major echo" were 85.3%, 88.0%, and 85.4%, and in "contains very hypoechoic echo" were 92.0%, 90.0%, and 92.4%. The analysis time of the CAD software was significantly shorter than for the sonographers (2.7 ± 1.6 vs. 29.7 ± 12.7 s, P < 0.001).

Conclusion: The CAD system achieved high accuracy in describing thyroid nodule features. It might assist in clinical thyroid nodule analysis.

计算机辅助诊断系统对甲状腺结节超声特征的诊断价值。

目的：探讨TUIAS（SW_TH01/II）计算机辅助诊断（CAD）软件系统对甲状腺结节超声甲状腺成像报告和数据系统（TI-RADS）特征的诊断价值。材料和方法：这项回顾性研究纳入了2017年1月至2021年10月在上海东方医院就诊的甲状腺结节患者。新型CAD软件（SW_TH01/II）和三名声谱学家对甲状腺结节的纵横比、边缘不规则、边缘平滑、钙化和回声等超声TI-RADS特征进行了定性分析。结果：共有225名患者入选。CAD软件在“长宽比”中的准确度、灵敏度和特异性分别为95.6%、96.2%和95.4%，在“边缘不规则”中的准确性、灵敏度和特异度分别为90.7%、90.5%和90.9%，在“边界平滑度”中的精确度、灵敏度和专异度分别分别为85.8%、88.5%和83.0%，在“钙化”中的灵敏度和特异性分别为83.6%、81.7%和82.0%，在“包含极低回声回声”中分别为92.0%、90.0%和92.4%。CAD软件的分析时间明显短于声谱仪（2.7±1.6 vs.29.7±12.7 s，P<0.001）。结论：CAD系统在描述甲状腺结节特征方面具有较高的准确性。它可能有助于临床甲状腺结节分析。

期刊介绍： The Archives of Endocrinology and Metabolism - AE&M – is the official journal of the Brazilian Society of Endocrinology and Metabolism - SBEM, which is affiliated with the Brazilian Medical Association. Edited since 1951, the AE&M aims at publishing articles on scientific themes in the basic translational and clinical area of Endocrinology and Metabolism. The printed version AE&M is published in 6 issues/year. The full electronic issue is open access in the SciELO - Scientific Electronic Library Online e at the AE&M site: www.aem-sbem.com. From volume 59 on, the name was changed to Archives of Endocrinology and Metabolism, and it became mandatory for manuscripts to be submitted in English for the online issue. However, for the printed issue it is still optional for the articles to be sent in English or Portuguese. The journal is published six times a year, with one issue every two months.
