摘要
目的探析低剂量多层螺旋CT(MSCT)对肺部真菌感染的诊断意义。方法选取2017年2月至2018年10月于我院进行诊治的40例肺部真菌感染患者为研究对象,均经病原学检查确诊为肺部真菌感染,并采用低剂量MSCT进行检查,观察CT诊断结果并分析其影像学特征。结果纳入患者依据CT影像的主要表现进行分型,其中共有4例结节或肿块为主型(10.00%),13例曲霉菌球型(32.50%),14例弥漫型(35.00%),9例类似肺炎型(22.50%);患者中10例为单纯性病变(25.00%),30例为混合性病变(75.00%)。CT影像特征性表现主要有结节或肿块阴影、晕轮征、空洞、洞中球征、楔形实变征、冰针征、新月征、枝芽征等,且存在多种征象并存的情况。结论肺部真菌感染在CT影像中具有较为明显的特征性,依据各种CT征象可观察到肺部病灶大小、形态、病变程度等基本情况,为疾病诊断和治疗提供依据。
Objective To explore the diagnostic significance of low-dose multi-slice spiral CT(MSCT)in pulmonary fungal infection.Methods Forty patients with pulmonary fungal infections diagnosed by etiological examination from February 2017 to October 2018 in our hospital were selected as the study objects.Low-dose MSCT was used to examine,the results of CT diagnosis were observed and the imaging characteristics were amelyzed.Results The patients were classified according to the main manifestations of CT images,including cases of 4 cases of nodules or masses(10.00%),13 cases of aspergillosis(32.50%),14 cases of diffuse(35.00%)and 9 cases of pneumonia-like(22.50%).Among the patients,10 cases were simple lesions(25.00%)and 30 cases were mixed lesions(75.00%).The characteristic manifestations of CT imayes include nodule or mass shadow,halo sign,cavity,globe sign in cave,wedge consolidation sign,ice needle sign,crescent sign,branch and bud sign,and there are many signs coexisting.Conclusion Pulmonary fungal infection has obvious characteristics in CT images.According to various CT signs,it can observe the size,shape,degree of lesion and other basic conditions,which can provide basis for disease diagnosis and treatment.
