探讨CT高分辨扫描在婴幼儿支气管肺发育不良诊治中的应用

目的：探讨CT高分辨扫描在婴幼儿支气管肺发育不良（BPD）诊治中的应用。方法：对比分析本院近三年来确诊为BPD且进行过胸部CT检查的患儿50例,患儿的临床首次诊断年龄为1天—2个月,病例分为低剂量组（A组）25人及高分辨组（B组）25人,检查所用CT机为Toshiba Aquilion 64排螺旋CT。结果：A组影像诊断符合率为92%,B组影像诊断符合率为96%。结论：CT高分辨扫描在婴幼儿支气管肺发育不良诊治中的优势不明显但明显提高了患儿的受辐射剂量,不推荐使用。

Objective： To evaluate the application of High Resolution CT（HRCT）in the diagnosis and treatment in infants with bronchial pulmonary dysplasia（BPD）. Methods： Comparative analysis of 50 confirmed cases diagnosed with BPD and had thoracic CT with Toshiba Aquilion 64 slice spiral CT in recent three years. The patients first di agnosed at 1 days to 2 months old were divided into low dose group （group A） and high resolution group （group B） averagely. Results： The accurate rate of diagnosis was 92% for group A and 96% for group B. Conclusion： The advantage of HRCT in the diagnosis and treatment of infants with BPD is not obvious but significantly improves the radiation dose in children , does not recommend to use.
