Abstract:
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.
