摘要 目的分析肺部真菌感染应用多排螺旋CT诊断的价值。方法选取本院2015年6月至2018年6月收治的107例肺部真菌感染患者作为Ⅰ组,均行CT和X线检查。选取同期肺结核患者46例归入Ⅱ组和肺癌患者42例归入Ⅲ组作为参照,患者均行肺部CT检查,以肺部真菌感染患者穿刺活检结果为参照标准,分析CT诊断征象及结果。结果根据肺组织穿刺活检结果可知,Ⅰ组肺部真菌感染患者病原菌感染类型包括曲霉菌(41.12%),隐球菌(31.78%),白色念珠菌(17.76%),胞浆菌(7.48%),毛霉菌(1.87%);以此为参考依据发现,CT诊断肺部真菌感染的符合率(73.83%)明显高于X线诊断的(28.97%)(P<0.05);肺部真菌感染患者CT征象分布包括斑片、结节型(49.93%),肿块型(37.38%),实变型(18.69%);由CT平扫征象分布状态可知,肺部真菌感染患者的晕征、短毛刺、长毛刺、支气管充气征、深分叶、浅分叶征象占比(61.68%、50.47%、56.07%、61.68%、67.29%、33.64%)明显高于肺结核患者(15.22%、10.87%、19.57%、8.70%、0、8.70%),淋巴结肿大、钙化、卫星灶征象占比(14.95%、9.35%、5.61%)明显低于肺结核患者(54.35%、63.04%、47.83%)(P<0.05);肺部真菌感染患者的晕征、长毛刺、支气管充气征、深分叶等征象占比(61.68%、56.07%、61.68%、67.29%)明显高于肺癌患者(19.05%、30.95%、19.05%、45.24%),淋巴结肿大、空泡征、凹陷征占比(14.95%、9.35%、9.35%)明显低于肺癌患者(57.14%、52.38%、38.10%)(P<0.05)。结论肺部真菌感染患者CT征象各异,根据患者CT影像学表现可有效鉴别肺部真菌感染病例,具有重要的临床应用价值。 Objective To analyze the value of multi-slice spiral CT in the diagnosis of pulmonary fungal infection. Methods Picking June 2015 to June 2018 107 cases of pulmonary fungus infection were treated as Ⅰ group, both CT and X-ray examination. Selection of 46 cases of tuberculosis patients in the same period Ⅱ group and 42 patients with lung cancer in Ⅲ group as a reference, the patients were lung CT examination, with pulmonary fungal infection in patients with biopsy results as the reference standard, analyzing CT signs and results. Results According to the result of lung tissue biopsy,Ⅰ group of patients with pulmonary fungal infection pathogenic bacteria types including aspergillus infection (41.12%), cryptococcus (31.78%), candida albicans (17.76%), cytoplasm bacteria (7.48%), mucor (1.87%). Based on this, it was found that the coincidence rate of CT diagnosis of pulmonary fungal infection (73.83%) was significantly higher than that of X-ray diagnosis (28.97%)(P<0.05). The distribution of CT signs in patients with pulmonary fungal infection included plaque, nodular type (49.93%), mass type (37.38%), and solid type (18.69%). According to the distribution of the signs on plain CT scan, the proportion of signs of halo, short burr, long burr, air bronchogram, deep lobed and shallow lobed in patients with pulmonary fungal infection (61.68%, 50.47%, 56.07%, 61.68%, 67.29%, 33.64%) was significantly higher than that in patients with pulmonary tuberculosis (15.22%, 10.87%, 19.57%, 8.70%, 0, 8.70%). The proportion of lymph node enlargement, calcification and satellite lesions (14.95%, 9.35%, 5.61%) was significantly lower than that of tuberculosis patients (54.35%, 63.04%, 47.83%)(P<0.05). Lung fungal infection in patients with halo sign, long burr, air-filled bronchi), such as deep lobulated sign proportion (61.68%, 56.07%, 61.68%, 67.29%) was significantly higher in patients with lung cancer (19.05%, 30.95%, 19.05%, 45.24%), lymph node enlargement, cavitation levy, depression patients than (14.95%, 9.35%, 9.35%),
