高频超声对甲状腺微小乳头状癌的诊断价值

目的:分析甲状腺微小乳头状癌(PTMC)的高频超声图像特征并探讨其鉴别诊断价值.方法:选取PTMC 72个结节及同期最大直径≤10 mm的良性结节68个进行对比研究.结果:除内部回声均匀程度外,其余10个超声特征在良恶性结节间均差异有统计学意义.本研究中5个征象灵敏度＞70.0％;4个征象特异性＞95.0％.超声诊断PTMC的敏感度和特异度分别为98.6％、88.2％.结论:高频超声是鉴别诊断PTMC的有效方法.

Value of High-Resolution Ultrasonography in Differential Diagnosis of Papillary Thyroid Microcarcinomo

Objective:To analyze ultrasonographic features of papillary thyroid microcarcinomo with high-resolution ultrasound,and to study its value to the differential diagnosis.Methods: 72 papillary thyroid carcinomo and maximum diameter of ≤ 10 mm over the same period of the 68 benign nodules were compared.Result: Except internal echo uniformity coefficient,with 10 ultrasonographic features,statistical significance was noted between benign and malignant micro-nodules of thyroid.In this study,the 5 ultrasonographic features,their sensitivity>70%;the 4 ultrasonographic features,their specificity >95.0%.The sensitivity and specificity of the high-ultrasonography in diagnosing PTMC is 98.6%,88.2%.Conclusion: High-resolution ultrasonography is very useful in differential diagnosis of papillry thyroid microcarcinomo.
