摘要: 目的 探讨螺旋CT平扫及增强时甲状腺结节CT值变化对良、恶性甲状腺结节的诊断价值.方法 回顾昆明医学院第一附属医院2009年3月到2010年3月间具有完整CT、手术、病理结果的47例甲状腺结节病例,结合病理表现对其平扫及增强时结节的CT值变化进行分析.结果 CT平扫值、延迟20秒增强CT值及延迟60s增强CT值在不同性质甲状腺结节之间差异均有统计学意义(P＜0.05).结论 螺旋CT平扫及增强时甲状腺结节的CT值变化对良、恶性甲状腺结节的鉴别具有一定意义;增强扫描以延迟20s增强较延迟60s增强对良、恶性甲状腺结节的鉴别更有价值.Abstract: Objective To study the value of plain and enhanced CT value changes with spiral CT in the differentiation of benign from malignant thyroid nodules.Methods 47 cases of thyroid nodules confirmed surgically and pathologically from march 2009 to march 2010 were observed retrospectively,then the plain and enhanced CT values of them were anlysed in detail.Result The differences in plain CT value,20 s CT value and 60 s CT value between different groups were statistically significant(P<0.05).Conclusions The changes...
