Cardiovascular MRI Reference Ranges for Heart, Aorta, and Pulmonary Artery in Healthy Chinese Children

Background Cardiovascular magnetic resonance (cardiac MR) reference ranges in Chinese children are lacking. Purpose To establish age‐ and sex‐specific reference ranges for cardiac MR parameters in a cohort of healthy Chinese children. Study Type Retrospective. Subjects One hundred ninety‐six healthy children (mean age 9.5 ± 3.6 years, 111 boys). Field Strength/Sequence 1.5 T; balanced steady‐state free precession. Assessment Biventricular volume and ejection fractions (EF), left atrial (LA) volume, right atrial (RA) area, left ventricular (LV) mass and thickness, aortic root (AR), and main pulmonary artery (MPA) dimensions were measured. Parameters were compared between age groups and sex. The relationships between parameters and age, body mass index (BMI) and body surface area (BSA) were investigated. Statistical Tests Independent‐samples t tests; Pearson's correlation. A P value
