Quantitative Ultrasound to Assess Steatotic Liver Disease in Children

Participants will undergo an advanced magnetic resonance (MR) examination of the abdomen and liver.

Participants will undergo an abdominal ultrasound (US) examination using a full-size US system. Some participants may undergo a point-of-care abdominal US exam with a handheld US system, if possible.

Participants will undergo a blood draw of approximately 25 mL volume.

Participants will have their height, weight and waist circumference measured. Vital signs including respiratory frequency, heart rate, temperature, and blood pressure will be measured.

Participants will be asked to fill out questionnaires to collect information about their prescribed medications, demographics, medical and surgical histories, prior laboratory results, physical activity and lifestyle measures, and potential alcohol intake (AUDIT questionnaire).
