Magnetic Resonance Imaging to Assess Body Composition Change in Adolescents With Obesity After Sleeve Gastrectomy

Objectives: Metabolic and bariatric surgery is the most effective weight loss treatment for severe obesity. The number of adolescents undergoing sleeve gastrectomy is increasing. We investigated changes in body composition in adolescents undergoing sleeve gastrectomy 12–26 weeks post-operatively using whole-body magnetic resonance imaging (WB-MRI). Methods: This prospective cohort study assessed changes in adipose tissue compartments (ie, visceral, subcutaneous, and intermuscular) and muscle in 18 obese adolescents, ages 14–19, 89% female, with body mass index z-score of 2.6 ± 0.25 (range 2.16–3.2). All underwent WB-MRI 1.5–17 weeks pre-operatively and 12–26 weeks post-operatively. Results: Pre- and post-operative WB-MRI showed decreases in all adipose tissue compartments, as well as decreased skeletal muscle and liver fat fraction (P
