超声评分法在良恶性甲状腺结节鉴别中的临床研究

The clinical study on differentiation of benign and malignant thyroid nodules by ultrasound scoring method

目的通过甲状腺结节超声评分法,探讨一种准确率高,容易为超声医师掌握和量化的评估方法。方法对我院超声检出并经病理确诊的90例甲状腺结节进行回顾性评分,利用甲状腺结节超声评分法,计算超声评分法判断甲状腺结节良恶性的敏感性、特异性、阳性预测值及阴性预测值,拟定甲状腺良恶性结节评分临界值。结果甲状腺结节超声评分法诊断甲状腺癌的敏感性为94.1%,特异性为96.6%,假阳性预测值为94.1%及假阴性预测值为96.6%;而良恶性结节评估的最佳临界值为7分。结论甲状腺结节超声评分法提高了良恶性甲状腺结节定性评估的准确率,特别是对微小癌的诊断更具有较高的临床价值,弥补了传统超声评估法存在尺度把握较难,认知差异较大等不足。

Objective To explore a high accurate and easy evaluation method by thyroid lesions ultrasound scoring. Methods Ninety cases of thyroid nodules detected by ultrasound and confirmed by pathology were reviewed, ultrasound evaluation scoring of the benign and malignant thyroid nodules was performed. The sensitivity, specificity, positive predictive value and negative predictive value of the method was calculated. The score threshold for benign and malignant thyroid nodules was developed. Results The sensitivity of ultrasound scoring method for diagnosis of thyroid cancer was 94. 1%, the specificity was 96. 6%, the false positive predictive value was 94. 1% and the false negative predictive value was 96. 6%. The threshold score for distinguishing benign and malignant thyroid nodules was 7. Conclusion The ultrasound scoring method of thyroid nodule assessment can significantly improve the accuracy of benign and malignant thyroid nodules, it has high clinical value, especially for the diagnosis of minimum thyroid cancer, and made up for the shortage of traditional ultrasonic evaluation method which is more difficult to grasp, quite different in cognition.
