甲状腺癌的超声图像特征分析

Analysis of ultrasonic characteristics of thyroid carcinoma

目的:探讨二维超声和彩色多普勒超声诊断甲状腺癌的价值。方法:对42例经手术病理证实的甲状腺癌患者,术前超声测量甲状腺大小、回声及肿块病灶大小、形态、部位、数目、内部回声强度和均匀度、有无钙化、血流分布和血流阻力等指标。结果:形态不规则32例,不均匀性低回声34例,微小钙化28例,血流较丰富37例,阻力指数>0.7者30例。结论:甲状腺癌高频超声具有特征性表现,超声对甲状腺癌的诊断具有较高的临床价值。

Objective：To explore the clinical value of two-~timensional and color Doppler uhrasonography in the diagnosis of thyroid Carcinoma. Methods： Forty-two cases with thyroid carcinoma were confirmed by pathological examination. The size of the thyroid, echo, mass＇s size, shape,position, number,internal echo intensity and evenness, the calcification changes, the blood distributioncolor and the resistance index of blood of all cases were measured. Results ： In all patients, the lumps of 32 cases were abnormity, the heterogeneous echo of lumps of 34 cases were low,28 cases had small calcification ,37 cases had abundant blood flow and the resistance index of blood of 30 cases were less than 0.7. Conclusions ： The performances of uhrasonography of thyroid carcinoma have defin.ite features. It has important clinical value to diagnose thyroid carcinoma.
