【摘要】：目的探讨超声造影评分对甲状腺TI-RADS 4类单发实性结节良恶性的诊断价值,寻找降低4类结节穿刺率新方法。方法对131例TI-RADS 4类的甲状腺实性单发结节行超声造影检查,根据结节增强特性,获取其超声造影评分,以手术病理结果为金标准,绘制ROC曲线得出造影评分最佳界值。通过与界值比较,对4a类、4b类结节进一步调整,分析调整前、后TI-RADS 4类结节的诊断效能。结果最佳评分界值为2分。甲状腺TI-RADS 4a类、4b类结节经超声造影评分调整与病理比较,诊断准确度分别为82.4%、80.9%。调整前后ROC曲线下面积分别为0.779、0.860,Z=1.7,二者差异存在统计学意义(P0.05)。结论运用超声造影评分对甲状腺TI-RADS 4类结节进行调整,提高了甲状腺TI-RADS 4类结节的诊断效能,一定程度降低甲状腺结节穿刺活检率。
[Abstract]:Objective to investigate the ultrasound score on thyroid TI-RADS 4 value of single solid nodules in the diagnosis of benign and malignant nodules, for reduce the 4 puncture rate. Methods 131 cases of TI-RADS thyroid Solid 4 solitary nodules underwent contrast-enhanced ultrasound, according to the nodule enhancement, obtain the ultrasound score, with pathologic results the gold standard, the contrast score optimalcutoff ROC curve. With boundary value comparison, further adjustment of class 4A and class 4B nodules, analysis of the adjustment of the former diagnostic efficacy after 4 TI-RADS nodules. Results the best score value of 2 points. A comparison of 4 thyroid TI-RADS, 4b and pathological nodules after adjustment ultrasound score, diagnostic accuracy was 82.4%, 80.9%. before and after the adjustment of the area under the ROC curve were 0.779,0.860 and Z=1.7, there was significant difference between the two groups (P0.05). Conclusion the use of contrast-enhanced ultrasound on thyroid TI- score RADS 4 nodules were adjusted to improve the diagnostic efficiency of thyroid TI-RADS 4 nodules and to reduce the biopsy rate of thyroid nodules to a certain extent.
