Methods: taking the period from March 2021 to March 2022 as the study period, 80 children with suspected congenital heart disease treated in our hospital were enrolled. The routine iodine contrast agent scanning examination (370mgl/ml) was performed in group A, and the low concentration iodine contrast agent scanning examination (270mgl/ml) was performed in group B. the value of CTA images, the clarity of CTA images, and the uniformity of contrast agents in the two groups were observed and analyzed. Results: there was no significant difference in the CT value of cardiac cavity between the two groups (P > 0.05);There was no significant difference in CT value between the two groups (P > 0.05);The image clarity of group B was higher than that of group A (P;There was no significant difference in the uniformity of contrast medium between the two groups (P > 0.05). Conclusion: the application of CTA with low concentration iodine contrast agent in the diagnosis of children with congenital heart disease can not only reduce the renal burden of children, but also obtain higher definition CTA images, which is worthy of clinical promotion and application.展开更多
