Quantification of Pediatric Abdominal Organ Motion with a 4-Dimensional Magnetic Resonance Imaging Method

We quantified organ motion in 35 pediatric patients with a 4D MRI method and investigated the association between organ motion and specific patient characteristics. Organ motion was associated with patient age and anatomical site. Both inter-organ and intra-organ variations were apparent, and individual variation was greater in older patients. We analyzed the organ motion data to determine whether they could be used to predict organ motion in prospective patients.
