老年人肺结核的X线影像分析

X-ray imaging analysis of pulmonary tuberculosis in the elderly

目的:分析老年肺结核患者采用X线诊断的影像学特征,总结临床应用价值。方法:抽选我院于2013年1月至2016年1月期间收治的老年肺结核患者120例,均采用X线诊断,观察临床结果,分析影像学特征。结果:X线准确检出肺结核115例(95.8%),CT准确检出117例(97.5%),对比差异不明显(P>0.05)。结核病变部位:上肺部46例(38.3%)、中下肺部41例(34.2%)、双肺广泛分布33例(27.5%);影像学特征:纤维空洞性病变48例(40.0%),陈旧性钙化灶31例(25.8%),渗出增殖性病变25例(20.8%),干酪性肺炎16例(13.3%)。结论:老年肺结核患者的症状不典型、影像表现多变,X线诊断能够明确病变部位、类型,具有较高的应用价值,可以作为临床防治、预后评估的重要参考指标。

Objective To analyze the imaging features of x-ray diagnosis in elderly patients with pulmonary tuberculosis, and to summarize the clinical application value. Methods: 120 elderly patients with pulmonary tuberculosis were selected from January 2013 to January 2016. x-ray diagnosis was used to observe the clinical results and the imaging features were analyzed. Results 115 cases(95.8%) of pulmonary tuberculosis were detected accurately by x-ray, and 117 cases(97.5%) were accurately detected by CT. the difference was not significant(p> 0.05). The location of tuberculous lesions was 46 cases(38.3%),41 cases(34.2%) of the middle and lower lungs, and 33 cases(27.5%) with a wide distribution of the lungs. Imaging features: 48 cases(40.0%) of fibrous cavity lesions, 31 cases of old calcification(25.8%), 25 cases of exudative proliferative lesions(20.8%), and 16 cases of cheese pneumonia(13.3%). Conclusion the symptoms of elderly patients with pulmonary tuberculosis are not typical and the imaging manifestations are variable. x-ray diagnosis can identify the location and type of the disease, and has high application value. it can be used as an important reference index for clinical prevention and treatment and prognosis evaluation.
