Nonuniform flow dynamics in the aorta of normal children: A simplified approach to measurement using magnetic resonance velocity mapping

Abstract

Purpose: To determine regional flow dynamics in the normal aorta (Ao) in children. Understanding flow dynamics in children is important in cardiovascular energetics, in designing improved aortic reconstructions by crafting the surgery to mimic normal aortic flow, and in Doppler flow calculations. The objective of this study was to determine regional flow dynamics in the normal Ao in children. Materials and Methods: We performed magnetic resonance velocity mapping on 13 subjects (ages 7.2 ± 6.2 years) with normal Aos to determine flow dynamics in four equal quadrants in the ascending (AAo) and descending aorta (DAo) aligned along the long axis of the Ao. Statistical significance was set at P
