Abstract:

目的 探讨低剂量多层螺旋CT(MSCT)对肺部真菌感染的诊断价值。 方法 对106例经手术病理、真菌培养及临床治疗证实的肺部真菌感染患者的MSCT表现进行回顾性分析,所有患者进行低剂量MSCT检查(包括自动管电流调制技术和迭代重建技术),其中6例行CT增强扫描。 结果 106例肺部真菌感染患者MSCT中含有肺部多种基本影像表现,按其主要的基本影像表现分为斑片结节型54例,实变型38例,肿块型14例。106例MSCT表现中,呈现多灶性91例、多形性83例和多变性78例。本组具有特征性MSCT表现的病例中,枝芽征39例,晕轮征32例,楔形实变征19例, 冰针征15例,新月征11例,气环征6例,反晕征4例,空洞内结节无强化5例。 结论 肺部真菌感染具有一定的MSCT特征性表现,结合临床资料可对典型的肺部真菌感染者行MSCT诊断
