Whole body fat fraction was previously published by our group in term and preterm infants using Dixon CSI MRI. Advanced semi-automated regional fat quantification was performed yielding: subcutaneous adipose tissue(SAT), visceral adipose tissue(VAT), brown adipose tissue (BAT) volumes and hepatic fat fraction (HFF). Whole body VAT volume (cc) was increased in preterm infants (3.4%±1.5%) compared to term (2.4%±0.9%) (p=0.079) when normalized to total body volume (cc). HFF and BAT did not differ between term and preterm infants (p>0.25). CSI MRI allows quantification of regional fat depots in preterm infants which may potentially help optimize nutritional management and monitor growth.
