| 目的 探讨常规超声及超声弹性成像新评分标准(7分法)在甲状腺占位病变诊断中的应用价值。方法 经术后病理证实的68例(115个病灶)甲状腺占位病变患者,术前接受常规超声及实时超声弹性成像检查,观察病变的灰阶、彩色多普勒血流显像及弹性图特征。结果 常规超声诊断甲状腺结节的敏感度为80.00％、特异度为88.00％、准确率为85.22%。超声弹性成像图中良性病变以1~4分多见,而恶性病变以5~7分多见。以5分以上(含5分)作为判断恶性的标准,则其敏感度为87.50%,特异度为100%,准确率为95.65%。超声弹性成像诊断的准确率与常规超声比较,差异有统计学意义(P<0.05)。结论 在甲状腺占位病变的鉴别诊断方面,超声弹性成像能够提供较大帮助,可提高诊断准确率,但仍需结合常规超声进行诊断。 |

| Objective To explore the value of conventional ultrasound and new evaluated criteria (7 score method) of ultrasound elastography (UE) in the diagnosis of thyroid lesions. Methods Totally 68 patients (115 thyroid nodules) proved by pathology underwent preoperative conventional ultrasound and real-time ultrasound elastography. The features on gray scale, color Doppler flow imaging (CDFI) and elastogram were documented. Results The sensitivity, specificity and accuracy of conventional ultrasound in the diagnosis of thyroid nodules were 80.00％, 88.00％ and 85.22%. In ultrasound elastography imaging map, benign lesions of 1 to 4 score were more common and malignant lesions of 5 to 7 score were more common. With 5 or more score (including 5 score) as a standard to judge malignant, the sensitivity, specificity and accuracy were 87.50%, 100% and 95.65%. There was significant difference in accuracy between conventional ultrasound and ultrasound elastography (P<0.05). Conclusion In the differential diagnosis of benign and malignant thyroid lesions, the ultrasound elastography imaging can provide greater help, but still need to combine with conventional ultrasound for diagnosis. |
