目的:探讨64排螺旋CT回顾性心电门控成像对新生儿复杂性先天性心脏病(CHD)的诊断价值。方法:210例新生儿复杂性先天性心脏病患儿分别采用64排螺旋CT回顾性心电门控对比增强心脏成像扫描和普通对比增强心脏成像扫描方案,评价两组的图像质量和诊断结果。结果:研究组可评估和不可评估的图像为100.0%(114/114)、0%(0/114),对照组分别为97.9%(94/96)、2.1%(2/96),可评估图像两组的差异无统计学意义(P>0.05),而对于不可评估的图像两组差异有统计学意义(P<0.05)。研究组复杂性先心病诊断准确率和冠状动脉异常准确率分别为97.4%(111/114)和100.0%(6/6),对照组分别是94.8%(91/96)和50.0%(2/4),两组对复杂性先天性心脏病诊断准确率比较差异无统计学意义(P>0.05),但对冠状动脉异常准确率差异有统计学意义(P<0.05)。结论:64排螺旋CT回顾性心电门控成像可以提高新生儿复杂性先天性心脏病图像质量,提高新生儿复杂性先天性心脏病诊断准确率,尤其是提高伴有冠状动脉异常诊断的准确率。
Objective: To investigate the diagnostic value of 64-slice spiral CT retrospective ECG-gated in the diagnosis of neonatal complex congenital heart disease (CHD). Methods: A total of 210 neonates with complicated congenital heart disease were retrospectively evaluated by using 64-slice spiral CT retrospective electrocardiogram (GGCT) contrast-enhanced cardiac imaging and contrast-enhanced cardiac imaging. The image quality and diagnostic results of the two groups were evaluated. Results: The evaluable and non-evaluable images in the study group were 100.0% (114/114) and 0% (0/114) respectively, and the control group was 97.9% (94/96) and 2.1% (2/96) There was no significant difference between the two groups (P> 0.05), but there was no significant difference between the two groups (P <0.05). The diagnostic accuracy of CAD and CAD in the study group were 97.4% (111/114) and 100.0% (6/6) respectively, while the control group was 94.8% (91/96) and 50.0% (2 / 4). There was no significant difference in diagnostic accuracy rate between the two groups for complicated congenital heart disease (P> 0.05), but there was a significant difference in the accuracy rate of abnormal coronary arteries (P <0.05). Conclusion: 64-slice spiral CT retrospective ECG-gated imaging can improve the image quality of neonates with complicated congenital heart disease and improve the diagnostic accuracy of neonatal complicated congenital heart disease, especially to improve the accurate diagnosis of coronary artery abnormalities rate.
