目的:探讨低剂量多层螺旋CT在诊断肺间质性病变的应用价值。方法:选择我院2014年1月-2015年2月间收治的100例肺间质病变患者为研究对象,分别予以两种不同剂量的高分辨CT胸部扫描进分组,低剂量组:50例;常规剂组:50例;比较两者不同剂量下总体病变指标。结果:低剂量组与常规剂组的总体病变指标比较无差异(P>0.05),不具统计学意义;低剂量的单项指标略低于与常规剂量,但组间比较无明显差异(P>0.05),不具统计学意义。结论:低剂量多层螺旋CT扫描在肺间质病变的应用是可行的,可全面降低被检者40%左右的辐射量,且又不会影响临床医师的诊断分析。
Objective: To investigate the value of low-dose multi-slice spiral CT in the diagnosis of pulmonary interstitial lesions. Methods: A total of 100 patients with interstitial lung disease (TBI) admitted from January 2014 to February 2015 in our hospital were enrolled in this study. Two different doses of high resolution CT chest radiography were divided into two groups. The low dose group (n = 50) Conventional group: 50 cases; compare the two under different doses of the overall lesion. Results: There was no significant difference between the two groups (P> 0.05), but there was no significant difference between the two groups (P> 0.05). The single index of low dose group was slightly lower than that of conventional dose group ), Not statistically significant. Conclusion: The application of low-dose multi-slice spiral CT in the diagnosis of interstitial lung disease is feasible and can reduce the radiation dose of about 40% of the subjects, without affecting the clinician’s diagnosis.
