超声弹性成像鉴别甲状腺良恶性结节的应用价值

A Study of the Value of Elastosonography Application in Differentiating Benign from Malignant Thyroid Nodules

目的探讨超声弹性成像对甲状腺良恶性结节鉴别诊断的价值。方法应用超声弹性成像对42例患者共63个甲状腺结节进行检查,采用5级评分法进行评价,所有患者均经手术病理证实。结果甲状腺良性结节的弹性图分级多≤Ⅱ级,恶性结节多≥Ⅲ级。以≥Ⅲ级作为恶性结节的判定标准,其敏感度、特异度、准确性分别为85%、97.7%、93.7%,两组病变的弹性图像分级情况比较有明显差异(P<0.001)。结论超声弹性成像有助于甲状腺良恶性结节的鉴别。

Objective To evaluate the value of elastosonography in differentiating benign from malignant thyroid nodules.Methods 42 patients with 63 nodules were examined by elastosonography and compared with the pathology.Results The majority of benign thyroid nodules were scored less than Ⅱ grade,while the majority of malignant thyroid nodules were scored more than Ⅲ grade.Thus,the elasticity scores more than Ⅲ grade were highly predictive of malignancy（P0.001）,with a sensitivity of 85%,a specificity of 97.7%,a accuracy of 93.7%,there was statistically significant between them.Conclusions Elastosonography is helpful in differentiating between malignant and benign thyroid nodules.
