摘　　要：目的探讨血管指数(VI)对甲状腺机能亢进(甲亢)及桥本氏甲状腺炎(HT)的诊断价值。方法经临床及实验室检查明确诊断的甲亢患者97例,HT患者79例,正常对照组65例,均行超声检查并计算VI,比较3组之间的差异性。绘制甲亢与HT的受试者工作曲线(ROC曲线)并进行分析。结果 3组之间的总体均数有统计学差异(P<0.001),组间两两比较有统计学差异(P<0.001)。甲亢组与HT组较对照组血流明显增多,甲亢组较HT组血流增多。ROC曲线下面积0.848,以VI≥18.50作为甲亢与HT的诊断界点,敏感度与特异性分别为75.3%、81.0%。结论 VI作为血流检测的定量参数,能量化反映甲状腺实质内的血流情况,对甲亢与HT的诊断及其鉴别诊断有一定价值。Objective To explore the value of vascularity index in hyperthyroidism and Hashimoto＇s tbyroiditis （HT）. Methods All the cases including 97 cases for hyperthyroidism, 79 cases for HT,65 cases for control were ex amined with ultrasound and vascularity index were calculated automatically. The difference among them was analyzed. We drew receiver operating characteristic （ROC） curve of hyperthyroidism and HT. Results There is significant difference among the three groups and also between each two groups（P＇~0.00l）. The aera under ROC curve was 0. 848,if the cutoff value was equal or more than 18.50,the sensitivity and specificity was 75.3% ,81.0% ,respective ly. Conclusions Vascularity index was a promising quantitative method in reflecting the vascularity of thyroid parch chyma, and it was helpful in the differential diagnosis of hyperthyroidism and HT.
