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.
