| 目的 筛选影响甲状腺病灶良恶性的超声指标，探讨甲状腺影像报告和数据系统（TI-RADS）分类超声客观评价体系的建立及应用。方法 通过Logistic方程回顾性分析1 080例甲状腺结节超声图像表现，筛选出鉴别良恶性的超声指标，获得指标权重并赋值，开发TI-RADS分类分析软件。纳入332例甲状腺疾病患者验证TI-RADS分类超声客观评价体系的诊断效能。结果 共5项超声指标进入回归模型，分别为纵横比[优势比（OR）=3.61）]、边缘（OR=3.83）、成分（OR=11.46）、回声（OR=14.11）、微钙化（OR=48.82）。TI-RADS分类超声客观评价体系诊断332例甲状腺疾病患者的ROC曲线下面积为0.91（P<0.05）。结论 甲状腺病灶超声恶性指标的权重、形成的不同组合相比指标的数量，更值得关注。通过构建Logistic方程的TI-RADS分类超声客观评价体系具有较高的诊断效能。 |

| Objective To select the ultrasonic appearances which effect the benign and malignant of thyroid lesions, and to explore the establishment and applications of supersonic evaluation system for thyroid imaging reporting and data system (TI-RADS) classification. Methods The ultrasound images of 1 080 thyroid nodule cases were retrospectively analyzed by Logistic equation, and the ultrasonic appearances were screened to identify benign and malignant of thyroid lesions. All appearances were obtained weights. The TI-RADS classification analysis software was assigned, which was used to analyze 332 patients with thyroid diseases and to verify the diagnostic performance of the TI-RADS classification system. Results Five ultrasonic features were selected into the regression model, including aspect ratio (odds ratio[OR]=3.61), margins (OR=3.83), composition (OR=11.46), echogenicity (OR=14.12), microcalcification foci (OR=48.82). Using objective evaluation system for TI-RADS classification in ultrasound in diagnosing 332 cases, the area under the ROC curve was 0.91 (P<0.05). Conclusion Relatively the weight and formation of malignant indicators should be more concern than the number of ultrasonic malignant thyroid lesions indicators. The objective evaluation system for TI-RADS classification in ultrasound has relatively high diagnosis capability which established by the methods of Logistic equation. |
