老年肺结核病患者的X线及CT影像学诊断分析

摘要

Objective:To explore the imaging features of X-ray and CT in elderly patients with pulmonary tuberculosis.Methods:64 elderly patients with pulmonary tuberculosis were selected.Chest X ray was taken in all patients.Among them,27 cases were examined by CT.The ability of two kinds of imaging diagnosis of pulmonary tuberculosis were compared.We observed and analyzed the diagnostic accuracy of the disease,the nature of the lesion and the shape of the lesion.Results:The pathological characteristics of the patients were mainly cavity lesions,fibers and calcification,lymph node enlargement,exudation and nodules. From the detection rate and diagnostic accuracy of the lesion morphology,the detection rate of CT was higher than that of X-ray. Conclusion:The imaging manifestations of senile pulmonary tuberculosis is not typical.The clinical diagnosis and analysis of X-ray plain film and CT image should be carried out in clinic.%目的：探讨老年肺结核的X线及CT的影像特征。方法：收治老年肺结核患者64例，均拍胸部X线，其中27例又经CT检查，对两种影像诊断肺结核的能力进行比较，观察、分析该病的诊断准确率、病变性质及病灶形态。结果：患者的病变性质主要是空洞病变、纤维及钙化、淋巴结增大、渗出及结节；从病灶形态的检出率及诊断准确率来看，CT的检出率均高于X线。结论：老年肺结核的影像学表现呈不典型性，在临床上应将患者的X线平片与CT影像进行综合性诊断分析。
