【摘要】：目的探讨声辐射力脉冲成像中声触诊组织成像(VTI)技术的弹性图分级法和面积比在甲状腺实性结节良恶性诊断中的价值。方法对152例甲状腺结节患者的194个实性结节行常规超声、超声弹性成像(EI)和VTI检查。绘制受试者工作特征曲线(ROC曲线),研究VTI弹性图分级、面积比和超声EI弹性图评分在鉴别诊断甲状腺良恶性结节中的价值及诊断表现。结果甲状腺恶性结节(甲状腺癌)的VTI弹性图分级显著高于良性结节(P0.001);且恶性结节的VTI面积比显著大于良性结节(P0.001)。ROC曲线分析结果显示:VTI弹性图分级法的最佳阈值为Ⅳ级;面积比的最佳阈值为1.05;VTI弹性图分级的ROC曲线下面积显著大于超声EI弹性图评分法和VTI面积比(P0.05)。结论 VTI弹性图分级法和面积比可为甲状腺实性结节良恶性鉴别诊断提供有用信息,且VTI弹性图分级法的诊断价值高于超声EI弹性图评分法和VTI面积比。
[Abstract]:Objective to evaluate the value of acoustic palpation tissue imaging (VTI) in the diagnosis of benign and malignant solid thyroid nodules. Methods 194 solid nodules in 152 patients with thyroid nodules were examined by conventional ultrasound, (EI) and VTI. Objective: to draw the operating characteristic curve (ROC curve) of the subjects, and to study the value and the diagnostic manifestation of VTI elastogram grade, area ratio and EI-elastography score in differential diagnosis of benign and malignant thyroid nodules. Results the VTI elastogram grade of malignant thyroid nodules (thyroid carcinoma) was significantly higher than that of benign nodules (P0. 001), and the VTI area ratio of malignant nodules was significantly larger than that of benign nodules (P0. 001). The optimum threshold of area ratio was 1.05% VTI elastic chart classification, the area under ROC curve was significantly larger than that of ultrasound ei elastic chart scoring method and VTI area ratio (P0.05). Conclusion VTI elastogram classification and area ratio can provide useful information for the differential diagnosis of benign and malignant thyroid solid nodules, and the diagnostic value of VTI elastogram grading method is higher than that of ultrasound ei elastogram scoring method and VTI area ratio.
