超声弹性成像在甲状腺微小癌诊断中的应用价值

目的研究并分析超声弹性成像在甲状腺微小癌诊断中的临床意义,旨在于提高临床诊治中对甲状腺微小癌的早期诊断精确性。方法采用2011年3—12月进行甲状腺超声健康体检中发现的364个直径≤1.0cm实质低回声结节进行超声弹性成像检查,按5分法对甲状腺结节弹性图像进行评分,分值在0～2分之间判定为甲状腺良性结节,分值在3～4分之间判断为甲状腺恶性结节,分析87例经手术和病理证实的甲状腺微小癌的彩色多普勒超声弹性成像及病理资料。结果 364个结节,评分0分的0个,1～2分的277个,3～4分87个。≥3分的87个结节病理结果：乳头状癌74个,滤泡癌8个,髓样癌3个;腺瘤2个。结论超声弹性成像对甲状腺微小癌的诊断有较高的应用价值。

The Value of Ultrasound Elastography in the Diagnosis of Thyroid Microcarcinoma

Objective Discuss the application value of ultrasonography elastography in diagnose thyroid cancer. Methods Use the 453 examples （512 nodules） which discovered in thyroid ultrasonography medical health examination during March 2011 to June 2011. Divided them into 5 grades,use grade 0 to grade 2 as the diagnosis standard of judge benign thyroid nodules, use grade 3 to grader4 as the diagnosis standard of judge malignant thyroid nodules, then compare with the pathology results. Results Among 512 nodules, there are 456 nodules in grade 0 to grade 2,and 56 nodules in grade 3 to grade 4. The pathology results of 56 nodules： 47 papillary carcinomas, among them there are 31 occult carcinomas; 3 follicular carcinomas, among them there is 1 occult carcinoma; 2 medullary cancers; 4 adenomas. Conclusion Ultrasound elastography has high application value for thyroid cancer diagnosis.
