摘要
目的:探讨超声检查对甲状腺恶性肿瘤的诊断价值。方法:对我院经病理证实的54例甲状腺恶性肿瘤患者的超声检查结果做回顾性分析。结果:48例(89%)病变为低回声;43例(79%)病变边界模糊或欠整齐;40例(74%)内见微小钙化灶;46例(85%)内部回声不均匀。彩色多普勒血流显像(color doppler-flow imaging,CDFI)示54例(100%)病灶内均可探及血流信号;34例明显血流较为丰富杂乱;RI>0.60者33例,RI<0.60者21例。结论:甲状腺恶性肿瘤多数具有特征性表现,超声检查有助于恶性病例的诊断及对可疑病例的筛选,但诊断特异性尤其对微小病变良恶性的判断上有局限性,仍需进一步探讨。
Objective：To detect malignant thyroid tumor with ultrasound and color Doppler. Methods： Fifty - four patients who were confirmed by histo - pathology as malignant thyroid tumors were reviewed. Results. fouty- eight tumors（89 % ） showed hypoechogenicity, 43 （ 79 % ） tumors were nodular and innegular, 40 （ 74% ） tumors were microcalcified. Color Doppler Flow Imaging showed Arterial blood flow in all tumers. 33 tumors showed RI higher than 0.60.Conclusion：The sonographic sighs of most malignant thyroid tumors hold characteristics favourable in diagnosis, but it＇s difficult for ultrasound to determines minimal malignant.
