【摘要】 目的:探讨64层螺旋CT在甲状腺结节性病变诊断中的价值。方法:回顾性分析经手术病理证实的甲状腺结节性病变44例。所有病例均接受CT检查,包括平扫、动脉期(35S)、静脉期(50S)扫描。结果:CT对甲状腺腺瘤诊断符合率为67%,对结节性甲状腺肿诊断符合率为70%,对甲状腺癌诊断符合率为69%。结论:64层螺旋CT增强扫描对于甲状腺良、恶性病变的鉴别诊断有一定的参考价值。更多还原

【Abstract】 Objective:To investigate the value of 64-slices helical CT in diagnosis of thyroid nodules. Methods:44 cases with thyroid nodules proved surgically and pathologically were retrospectively analyzed. Before operations,all cases underwent CT examinations,including plain and contrast enhanced scanning in which arterial phase was done with the delay time of 35 seconds and venous phase 50 seconds after the beginning of contrast medium injection. Results:The diagnosis accordance rate of CT was 67% in thyroid adenoma,70% in struma nodosa and 69% in struma maligna. Conclusion:64-slices helical CT was helpful to differentiate the malignant from the benign thyroid nodules according to the enhancement pattern and extent during the contrast enhancement examination.更多还原
