目的:研究肺间质改变为主的肺结核CT检查表现及临床应用价值。方法:选择2014年2月-2015年2月我院接收的38例经CT检查结果为肺间质改变为主,经病理确诊的肺结核患者为研究对象,对所有患者在接受抗结核治疗前后给予CT检查,并对肺间质改变为主的肺结核CT检查结果进行分析。结果:与抗结核病治疗前相比,治疗后3个月、9个月以及12个月,所有患者CT征象检出率均明显下降(P<0.05)。结论:针对肺间质改变为主的肺结核患者在抗结核治疗前后进行CT检查,能够将其临床特征和改变特点清晰显现,在临床诊断、治疗和预后评价中有重要意义。 Objective: To study the CT findings of pulmonary tuberculosis and its clinical value. Methods: From February 2014 to February 2015, 38 cases of pulmonary tuberculosis patients who were diagnosed by pathological examination after the CT examination were taken by our hospital from March 2014 to February 2015 were selected as study subjects, and all patients were given before and after receiving anti-TB treatment CT examination, and pulmonary interstitial lung tuberculosis CT examination results were analyzed. Results: Compared with that before anti-tuberculosis treatment, the detection rate of CT signs was significantly decreased in all patients at 3 months, 9 months and 12 months after treatment (P <0.05). Conclusion: CT examination of patients with pulmonary tuberculosis, which is mainly pulmonary interstitial changes before and after anti-TB therapy, can clearly show its clinical features and changes, which is of great significance in clinical diagnosis, treatment and prognosis evaluation.
