摘　　要：目的探讨超声弹性成像在甲状腺良、恶性肿瘤鉴别诊断中的应用价值。方法对本院82例患者(103个甲状腺实性肿瘤)的常规超声及超声弹性成像特征进行对照分析(超声弹性成像诊断采用5级法),并将诊断结果与术后病理结果进行比较,评价两种方法对良、恶性甲状腺肿瘤的诊断准确性。结果 103个甲状腺肿瘤中,经病理证实良性肿瘤86个,其中弹性成像5级法诊断1级64个,2级15个,3级5个,4级2个;恶性肿瘤17个,其中弹性成像5级法诊断3级1个,4级9个,5级7个,若以硬度评级≥4级为界值,超声弹性成像诊断甲状腺恶性肿瘤的敏感度、特异度和准确率分别为94.1%(16/17),97.7%(84/86),97.1%(100/103);常规超声诊断的敏感度、特异度、准确率分别为82.4%(14/17)、88.3%(76/86)、87.4%(90/103),差异具有统计学意义(P<0.05)。结论超声弹性成像通过评价组织相对硬度来判别甲状腺肿瘤的性质,对于提高甲状腺肿瘤良恶性诊断的准确性具有较大帮助。Objective To discuss the clinical applications value of ultrasound elastography technology in diagnosing thyroid benign and malig-nant nodule .Methods Preoperative conventional ultrasonic nodules and ultrasound elastography characteristics By operation and pathology of 82 cases thyroid tumor patients (103 tumors) were retrospectively analyzed ,and compared with pathology .To evaluate the precision of the two dignon-sis way about thyroid tumor .Results All 86 benign tumors were confirmed by pathology in 103 thyroid nodule ,64 were I grade ,15 were Ⅱ grade , 5 were III grade ,2 were IV grade;17 benign tumors were confirmed by pathology in 103 thyroid tumors ,1 were III grade ,9 were IV grade ,7 were V grade ,The sensitivity ,Specificity and Precision Of the ultrasound elastosonography in differentiating benign and malignant thyroid tumors was 94.1% (16/17) ,97.7% (84/86) and 97.1% (100/103) ,was higher than that of conventional ultrasound 82.4% (14/17)、88.3% (76/86) and 87.4% (90/103) ,(P<0 .05) .Conclusion The Ultrasound elastosonography Technology can provide information on the flexibility of tissue ,can improve the efficiency of differential diagnosis Of in benign and malignant thyroid tumors .
