摘要

目的：

探讨声弹性成像5分评分法在甲状腺结节良恶性鉴别诊断中的价值。

方法：

本次研究采用回顾性分析，共收集59例患者，总计85个甲状腺结节。根据手术病理结果，将这85个结节分为良性组[42例，共63个结节，男性∶女性=21∶42，年龄13~74岁，平均(53.1613.00)岁

]

和恶性组[17例，共22个结节，男性∶女性=5∶17；年龄24~68岁，平均(44.7711.51)岁

]

。分析弹性图像，评估组间弹性评分有无差异；勾画受试者工作特征曲线，获得弹性评分方法的鉴别诊断效能；并且计算截断点。

结果：

甲状腺良恶性结节组间弹性评分差异有统计学意义(非参数Mann-Whitney秩和检验，

=-9.517，

=0.000)；曲线下面积为0.886，鉴别诊断效能较高；弹性评分大于等于3分时(截断点=3)评判恶性甲状腺结节的特异度为78.0%，灵敏度为90.5%。

结论：

声弹性评分法可以有效提高甲状腺结节良恶性的鉴别诊断。

Abstract

Objective:

This study aimed to explore the diagnostic value of elastic sonography score method in the identification of benign and malignant thyroid nodules.

Methods:

A retrospective analysis was conducted in 59 cases (85 thyroid nodules). According to the pathological results

85 nodules were divided into benign group [n=42

63 nodules

male∶female =21∶42

13-74 years old

average (53.1613) years

]

and malignant group [

=17

22 nodules

male∶female=5∶17

24-68 years old

average (44.7711.51) years

]

. The elastic scores between groups were compared

and differential diagnosis ability of elasticity score was evaluated

by using receiver operating characteristic (ROC) curve. Through the calculation of the cut-off point

the diagnostic sensitivity and specificity of diagnosis of malignant thyroid nodules were improved by calculation the cut-off point..

Results:

The elastic scores of thyroid nodules between benign and malignant group were significantly different (non-parametric Mann-Whitney test

=-9.517

=0.000). The area under the ROC was 0.886. When the elastic score was greater than or equal to 3 points (cut-off point=3) the specificity for diagnosis of malignant thyroid nodules was 78.0%

the sensitivity was 90.5%.

Conclusion:

The elastic sonography scoring system could help to improve the differential diagnosis of benign and malignant thyroid nodules.
