摘　　要：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。Objective To explore the diagnosis value of the low dose multi-slice spiral computed tomography（ MSCT） imaging in pulmonary fungal infection in order to improve its diagnosis level. Methods CT manifestations of 106 cases of pulmonary fungal infection confirmed by operation,pathology,mycetes cultivation and follow-ups of clinical therapy were retrospectively analyzed. All cases underwent low dose MSCT examinations including CARE dose 4D and sinogram affirmed iterative reconstruction technology,and6 cases underwent contrast-enhanced CT scanning. Results Among the basic MSCT findings of pulmonary fungal infection,they showed patch-nodular type in 54 cases,solid variant in 38 cases,and tumor type in 14 cases. In all cases,91 cases displayed as mulifocality,83 cases as polymorphism and 78 cases as polytropy.Among the 106 cases with comparative distinctive MSCT manifestations,bud of branch sign were showed in39 cases,halo sign in 32 cases,wedge shape consolidation in 19 cases,ice needle sign in 15 cases,crescentic sign in 11 cases,air ring sign in 6 cases,and contra-halo sign in 4 cases. The nodules in the cavities were not enhanced in enhanced scan in 5 cases. Conclusions There are some distinctive MSCT findings in patients with pulmonary fungal infection. Pulmonary fungal infection can be diagnosed with typical MSCT findings in close combination with the clinical information.
