Zhongshan Daxue xuebao. Yixue kexue ban, 2008 【目的】 探讨冠状动脉的三维形态结构?变异及与冠心病(CAD)发生的相关关系?【方法】 用多层螺旋CT (MSCT)增强方法行冠状动脉造影,通过工作站三维重建处理,观察?测量冠状动脉的分支?位置?形态及其变异,并分析其与冠状动脉粥样硬化病变的关系?【结果】成功进行MSCT冠状动脉造影的病例1057人,发现冠状动脉狭窄面积 > 70%诊为冠心病352例?资料显示左侧优势型的冠心病发病数相对较少,而左冠状动脉主干发出角度较大?主干较短?冠状动脉开口于冠状动脉窦之外变异与冠心病发生有显著相关关系?【结论 ...

Zhongshan Daxue xuebao. Yixue kexue ban, 2014 摘 要: 【目的】 白血病合并肝脏真菌感染的病例比较罕见,本文通过总结经病理证实的病例的CT表现特点,以期提高对该病诊断的准确性? 【方法】 收集16例经病理确诊的白血病合并肝脏真菌感染的临床与影像学资料,全部患者均行上腹部CT平扫及双期增强扫描,回顾性分析其CT表现?【结果】 16例中CT发现肝肿大9例(56%)?肝内病灶CT表现分5型:Ⅰ型,单纯低密度型,平扫?动脉期呈低密度,门脉期呈低或等密度;Ⅱ型,环征,动脉期边缘强化,门脉期为等密度;Ⅲ型,靶征,动脉期中央呈小结节状强化,周围见低密度环 ...
