甲状腺癌的超声诊断分析

Ultrasonic diagnosis of thyroid cancer

目的提高甲状腺癌的超声诊断符合率。方法回顾分析经手术病理证实的37例甲状腺癌的声像图表现,总结其声像特征。结果37例甲状腺癌肿块大小形态不一,大部分呈不均匀低回声,小部分呈等或混合回声;肿块边界多数不清,不规整,个别边界清楚;40.54%显示点状强回声微钙化,10%伴弧形或斑块状粗钙化。结论边界不清、不规整,内部呈不均匀低回声,并见点状强回声钙化是甲状腺癌较典型的二维声像特征,具有较大的诊断意义;特征不全者必须结合彩色多普勒血流成像,综合分析,才能提高甲状腺癌的正确诊断率。

Objective To improve the correction of ultrasonic diagnosis of thyroid cancer. imaging expression in 37 cases with thyroid cancer proven by pathology were retrospectively analyzed and their imaging characteristics were summarized. Results The size and state of the mass in these 37 cases is not the same, the majority of them revealed low heterogeneous echo, and the minority of them revealed equal or mixed echo; the rim of the mass is unclear, unequal size, only one rim is clear. 40.54 % of them showed strong echo with punctate slight calcification, 10% of them with arc or plaque coarse calcification Conclusion Uncl ear, irregular rim and only one clear rim echo and the strong echo with punctate calcification are the typical characteristics of the two dimensional ultrasonic imaging in thyroid cancer, which is of significance in diagnosis of thyroid cancer. To improve the correct diagnosis rate, two- dimensional ultrasonic examination should be combined with color Doppler imaging for diagnosis of patients with thyroid cancer of incomplete characteristics.
