低剂量MSCT和消化道造影诊断小儿先天性膈疝的对比研究

Study on the diagnosis of children congenital diaphragmatic hernia by using MSCT and gastrointestinal radiography

目的对比研究低剂量多排螺旋CT(MSCT)和消化道造影(GI)检查对小儿先天性膈疝(CDH)的诊断。方法回顾性分析2013年1月至2015年3月我院收治的13例疑似CDH患儿为研究对象,其中6例行低剂量MSCT检查,6例行消化道造影检查;1例同时行低剂量MSCT和GI检查。比较两种检查方法诊断CDH的阳性符合率。结果 7例患儿行低剂量MSCT检查,术后诊断CDH阳性率85.7%(6/7),其中膈膨升患儿1例;7例患儿行GI检查,二者比较差异无统计学意义(P=1.000)。低剂量MSCT的平均辐射剂量为(1.58±0.14)m Sv。结论与GI检查相比,低剂量MSCT是一种简单、安全、非侵入性和有效的评价婴儿CDH的方法。

Objective The arm of this study was to compare the diagnosis of congenital diaphragmatic hernia by using low dose multisice spiral computed tomography（MSCT） and upper gastrointestinal radiography（GI）.Methods A total of 13 cases of neonatus hospitalized in our hospital during January 2013 and March 2015 and suspected with congenital diaphragmatic hernia were selected as study objects. 6 cases of them were diagnosed by low dose MSCT,and another 6 cases were diagnosis by GI,and 1 case underwent the diagnosis by low dose MSCT and GI. The positive coincidence of these two diagnosis methods was compared.Results Totally 7 cases of patients received low dose MSCT,and the positive coincidence was 85.7%（6/7） and one case was diagnosed as eventration of diaphragm. And 7 ceases of patients received the GI for diagnosis. The difference of coincidence between the two groups was not statistically significant（P = 1.000）. The radiation dosage of low dose was（1.58±0.14） mSv. Conclusions Compared with GI,low dose MSCT is a simple,safe,non-invasive and effective method for evaluating neonatal congenital diaphragmatic hernia.
