探讨低剂量螺旋CT用于肺结核诊断的可行性

Feasibility of Low Dose Spiral CT in the Diagnosis of Pulmonary Tuberculosis

目的:研究低剂量螺旋CT用于肺结核诊断的可行性。方法:选取于2015年1月—2017年1月间医院收治的肺结核患者240例进行研究,采用数字随机分组法,将进行研究的患者分为基础组和实验组,基础组患者120例采用常规剂量螺旋CT进行扫描,实验组患者120例采用低剂量螺旋CT进行扫描,探究两组患者的诊断检出率、误诊率、漏诊率。结果:基础组患者与实验组患者在漏诊率、诊断检出率、误诊率等三个方面进行比较,存在的差异明显(P<0.05)。结论:低剂量螺旋CT用于肺结核诊断具有较高的诊断价值,分辨率较高,辐射较小,值得临床广泛应用以及推广。

Objectivebjective To study the feasibility of low dose spiral CT in the diagnosis of pulmonary tuberculosis. Methodss 240 cases of pulmonary tuberculosis treated in hospital from January 2015 to January 2017 were studied.The patients were divided into basic group and experimental group by digital random grouping.120 cases in basic group were scanned with conventional dose spiral CT,and 120 cases in the experimental group were scanned with low dose spiral CT to explore the diagnostic detection rate and misdiagnosis of the two groups.Rate and rate of missed diagnosis.e the diagnostic detection rate and misdiagnosis of the two groups.Rate and rate of missed diagnosis.Results Results There were significant differences between the basic group and the experimental group in the following three aspects:missed diagnosis rate,diagnostic rate and misdiagnosis rate(P<0.05).Conclusionn Low dose spiral CT is of high diagnostic value in diagnosis of pulmonary tuberculosis,with high resolution and less radiation.It is worthy of wide clinical application and promotion.
