超声造影与微血管成像在甲状腺结节鉴别诊断中的价值

Value of contrast-enhanced ultrasound and microvascular imaging in differential diagnosis of thyroid nodules

目的比较超声造影与微血管成像在甲状腺结节鉴别诊断中的价值。方法选择本院收治的68例甲状腺结节患者为研究对象,患者均实施超声造影与微血管成像鉴别诊断,并与手术病理诊断结果进行对比,比较超声造影与微血管成像对甲状腺结节的诊断结果。结果经术后病理诊断,68例甲状腺结节患者,共有结节样病灶79个,良性结节33个(41.77%),恶性结节46个(58.23%)。微血管成像诊断甲状腺结节的灵敏度、阴性预测值显著高于超声造影(P<0.05)。结论在甲状腺结节鉴别诊断中,超声造影与微血管成像均具有较高的鉴别的价值,但后者恶性结节诊断效果更好,值得临床推广应用。

Objective To compare the value of contrast-enhanced ultrasound and microvascular imaging in differential diagnosis of thyroid nodules.Methods Sixty-eight patients with thyroid nodules admitted in our hospitalwere selected as study objects.All patients underwent contrast-enhanced ultrasonography and microvascular imaging,and the diagnosis results were compared with the result of operative pathological diagnosis.The results of contrast-enhanced ultrasonography and microvascular imaging in diagnosis of thyroid nodules were compared.Results Diagnosed by pathology after operation,there were 79 nodular lesions in sxty-eight patients with thyroid nodules,including 33 benign nodules(41.77%)and 46 malignant nodules(58.23%).The sensitivity and negative predictive value of microvascular imaging in the diagnosis of thyroid nodules were significantly higher than those of contrast-enhanced ultrasound(P<0.05).Conclusion In the differential diagnosis of thyroid nodules,contrast-enhanced ultrasonography and microvascular imaging have high differential diagnostic value,however,the latter is more effective in the diagnosis of malignant nodules,and worthy of clinical application.
