摘要
目的探讨320排宽探测器CT评估儿童先天性心脏病(CHD)术后心功能的可行性。方法对25例CHD术后患儿以320排宽探测器CT和3.0T MR设备进行扫描,分别利用相应心功能分析软件测量左右心室射血分数(EF)、舒张末期容积指数(EDVI)、收缩末期容积指数(ESVI)、每搏输出量指数(SVI)和心指数(CI),分析320排宽探测器CT与MRI测量结果的相关性和可重复性。结果CT测得左右心室EF、EDVI、ESVI、SVI、CI与MRI相应指标差异均无统计学意义(P均>0.05)且均具有良好相关性(r=0.62~0.97,P均<0.05);CT所测各指标均值均高于MRI;CT各心功能测量值重复性良好(ICC=0.85~0.98,P均<0.05),左心室容量指标(EDVI、ESVI、SVI、CI)的重复性好于右心室。结论320排宽探测器CT可用于评价CHD术后患儿心功能,对无法接受MR检查者具有重要价值。
Objective To explore the feasibility of 320 row wide-detector CT in evaluation on cardiac function in postoperative congenital heart disease(CHD)children.Methods Totally 25 postoperative CHD children underwent 320 row wide-detector CT and 3.0T MR cardiac scanning during following-up.The left and right ventricular ejection fraction(EF),end diastolic volume index(EDVI),end systolic volume index(ESVI),stroke volume index(SVI)and cardiac index(CI)were measured with corresponding cardiac function analysis software.The reproducibility of 320 row wide-detector results and their correlation with MRI results were compared and analyzed.Results No significant difference of EF,EDVI,ESVI,SVI and CI was found between 320 row wide-detector CT and MRI results(all P>0.05),and CT results had good correlation with MRI(r=0.62-0.97,all P<0.05).The mean values of all index measured with CT were higher than those with MRI.The reproducibility of CT for measuring cardiac function indexes were good(ICC=0.85-0.98,all P<0.05).The volume index(EDVI,ESVI,SVI,CI)of left ventricular showed better reproducibility than that of the right ventricular.Conclusion 320 row wide-detector CT could be used to evaluate cardiac function in postoperative CHD children,having a great value for those with contraindication for cardiac MR.
