摘要
目的探讨低剂量螺旋CT扫描在周围型肺癌诊断中临床应用价值。方法回顾性分析我院自2008年12月~2013年12月收治的30例经手术和病理证实周围型肺癌患者,在同一时间段内分别给予常规剂量螺旋CT扫描和低剂量螺旋CT扫描,比较两种检查方法对周围型肺癌征象的显示情况。结果肿瘤径线<5 mm,5~10mm及>10 mm低剂量螺旋CT扫描显示的数量分别为8例、12例、5例,合计25例,常规剂量螺旋CT扫描显示的数量分别为9例、14例及6例,合计29例,两组相比较差异无统计学差异(>0.05);低剂量螺旋CT扫描与常规剂量螺旋CT扫描相比,低剂量螺旋CT扫描对坏死、钙化、细短毛刺、分叶征、血管集束征、胸膜凹陷征及阻塞性肺炎或肺不张等周围型肺癌征象的显示率无显著降低,其差异不具有统计学意义(>0.05)。结论低剂量螺旋CT扫描在降低辐射剂量的同时,也可以清楚显示周围型肺癌的各种征象,在诊断周围型肺癌中具有较高的临床应用价值。
Objective Explore the low-dose spiral CT scanning in peripheral lung cancer diagnosis in the clinical application value.Methods Retrospective analysis since December 2008 to December 2013 were 30 cases confirmed by surgery and pathology of peripheral lung cancer patients,at the same time period were given routine dose spiral CT scanning and low-dose spiral CT scanning,compare two methods of checking to show signs of peripheral lung cancer.Results Tumor diameter line<5 mm,5~10 mm and>10 mm low-dose spiral CT scan revealed a number of 8 cases,12 cases,5 cases respectively,total 25 cases,conventional dose spiral CT scan showed the number of 9 cases,14 cases and 6 cases respectively,total 29 cases,no statistical y significant dif erence compared with the two groups(>0.05);Low-dose spiral CT scanning compared with conventional dose spiral CT scanning,low-dose spiral CT scanning of necrosis and calcification and fine short bur,Ye Zheng sign,blood vessels,cluster sign,pleural sag and obstructive pneumonia or atelectasis rate of peripheral lung cancer signs show no significant decrease,the dif erence is not statistical y significant(>0.05).Conclusion Low-dose spiral CT scanning in reducing radiation dose of at the same time,also can clearly show various signs of peripheral lung cancer,in the diagnosis of peripheral lung cancer has high clinical value.
