摘要
目的探讨彩超对甲状腺恶性肿瘤的诊断价值。方法对经手术后病理证实的76例甲状腺恶性肿瘤及50例甲状腺腺瘤的二维及彩色多普勒超声表现作回顾性分析。结果甲状腺恶性肿瘤67例(88%)病变为低回声,54例(75%)病变边界不清或欠规整,无声晕。39例(51%)病灶内可见微小钙化灶,甲状腺恶性肿瘤的血供以高阻力为特征,与甲状腺腺瘤比较差异有统计学意义(P<0.01)。结论多数甲状腺恶性肿瘤具有特征性表现,彩超检查有助于甲状腺恶性肿瘤的诊断。
Objective To evaluate the value of color Doppler ultrasonography in diagnosis of malignant thyroid tumor. Methods Seventy-six cases with thyroid malignant tumor and fifty cases with thyroid adenoma confirmed by pathology were analyzed comparatively with two-dimensional and color Doppler flow imaging （CDFI）. Results Sixty-seven thyroid malignant tumor （88%）showed low level echo, fifty-four tumor （75%） were nodular,irregular and no acoustic halo. Thirty-nine tumor（51% ）were microcalcified, the blood supply of thyroid malignant tumor were charactered as high resistance, there were significant differences to thyroid adenoma（ P 〈 0.01 ）. Conclusion Most of malignant thyroid tumor had the characteristic manifestation, the CDFI were helpful to diagnosis of malignant thyroid tumor.
