| 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. |
