彩色多普勒超声诊断甲状腺癌

目的 探讨彩色多普勒超声对甲状腺癌的诊断价值,提高甲状腺癌的诊断准确率.方法 分析经手术治疗并经病理诊断确诊的40例甲状腺癌患者的术前超声检查结果,观察甲状腺癌的二维声像图及彩色多普勒血流特征.结果 ①本组40例甲状腺癌中乳头状癌占多数,占87.5％（35/40）,多数癌肿结节与良性结节并存;②40例甲状腺癌（44个肿块）的主要声像图特点：肿块以实质性低回声为主,占77.27％;肿块多数边缘不光整,呈毛刺状、蟹足样;肿块内部多伴钙化（37/44,84.1％）,以微钙化为主（27/37,73.0％）;③肿块血供丰富,血流检出率95.45％,且以Ⅲ、Ⅱ级血流为主.结论 甲状腺癌超声声像图多变,检查中不仅要抓住甲状腺癌的主要声像图特征,还需多切面观察,综合分析判断,注重归纳总结,以提高甲状腺癌的诊断准确率.

The effect of color Doppler ultrasound in diagnosis of thyroid carcinoma

Objective To explore the value of color Doppler ultrasound in diagnosis of thyroid carcinoma and improve the accuracy of diagnosis of thyroid carcinoma. Methods Pre-operational ultrasonic characteristics of 40 patients with thyroid carcinoma which were confirmed by pathology were analyzed. To observe two-dimensional uhrasonography and color doppler flow characteristics of the thyroid carcinoma. Results （1）palillary carcinoma accounts for the majority of 40 cases of thrroid carcinoma, 87.5% （35/40）,coexist about the majority of tumor nodules and benign nodules; （2）The main sonographie characteristics on 40 cases of thyroid carcinoma （44 masses）were： a.the lump with substantial hypoe- choic,accounted for 77.27%. b.the majority of lump with irregular margin,burr shaped,crab pattern; c.calcifieation ap- pear in the lump （37/44,84.1%）, was given priority to with microcalcification（27/37,73.O%）; （3）abundant blood flow ap- pear in the lump, detection rate of 95.45%, and given priority to with m, II blood flow. Conclusion The uhrasono- graphic of thyroid carcinoma changeable,not only to emphasis the mainly uhrasonographic characteristics of thyroid carcinoma,also need to observe more than one section,comprehensive analysis and judgement,pay attention to the summary, in order to improve the accuracy of diagnostic rate of thyroid carcinoma.
