Abstract：Objective To investigate the application value of SE-EPI and TSE T1-weighted black blood sequences in children’s cardiac magnetic resonance imaging, and compare the display degree of the two sequences in children’s myocardium. Methods A total of 20 children who underwent cardiac MRI examination in our hospital were included. All patients were scanned with SE-EPI and TSE T1 black blood sequences and the diagnosis results were recorded. Two doctors used the 5-point blind method to evaluate the image quality, and those with more than 3 points could be diagnosed, while those with less than 3 points could not be used for diagnosis. Finally, kappa values of two doctor’s，blind scores were statistically analyzed. Results Among the 20 children, there were 2 cases of myocarditis, 1 cases of myocardiosis, 4 cases of arrhythmia, 2 cases of congenital heart disease, 5 cases of metabolic disease, 1 case of incomplete in compact of myocardium, 1 case of hyperplasia in spandex endocardium, 4 cases of normal. For the sequence of SE-EPI, 5 cases with score 4, 8 cases with score 3, 4 cases with score 2, 3 cases with score 1. For the sequence of TSE, 3 cases with score 4, 12 cases with score 3, 3 cases with score 2, 2 cases with score 1. Kappa value between the two observerswas 0.78. Conclusion The myocardial contrast of SE-EPI sequence is higher than that of TSE sequence, but the requirement of heart rhythm and respiration is higher than that of TSE sequence. SE-EPI sequence is suitable for children with arrhythmia and stable breathing, while TSE sequence is suitable for children with arrhythmia and large breathing range.
