| Summary: | Background
The relationship between pancreatic fat on imaging and metabolic co-morbidities has not been established in pediatrics. We sought to investigate the relationship between pancreatic fat measured by MRI and endocrine/exocrine dysfunctions along with the metabolic co-morbidities in a cohort of children.
Objective
To investigate relationships between pancreatic fat quantified by MRI and endocrine and exocrine conditions and metabolic co-morbidities in a cohort of children.
Materials and Methods
This was a retrospective review of pediatric patients (
n
= 187) who had a clinically indicated MRI examination between May 2018 and February 2020. After 51 patients without useable imaging data were excluded, the remaining 136 subjects comprised the study sample. Laboratory studies were assessed if collected within 6 months of MRI and patient charts were reviewed for demographic and clinical information. MRI proton density fat fraction (PDFF) sequence had been acquired according to manufacturer’s specified parameters at a slice thickness of 3 mm. Two blinded radiologists independently collected PDFF data.
Results
The median age at MRI was 12.1 (IQR: 9.0–14.8) years and the majority of patients were Caucasian (79%), followed by African American and Hispanic at 12% and 11% respectively. There was a higher median pancreas fat fraction in patients with exocrine conditions (chronic pancreatitis or exocrine insufficiency) compared to those without (3.5% vs 2.2%,
p
= 0.03). There was also a higher median fat fraction in the head of pancreas in patients with endocrine insufficient conditions (insulin resistance, pre-diabetes, type 1 and type 2 diabetes) compared to those without endocrine insufficiency when excluding patients with active acute pancreatitis (3.5% vs 2.0%,
p
= 0.04). Patients with BMI > 85% had higher mean fat fraction compared to patients with BMI ≤ 85% (head: 3.8 vs 2.4%,
p
= 0.01; body: 3.8 vs 2.5%,
p
= 0.005; tail: 3.7 vs 2.7%,
p
= 0.049; overall pancreas fat fraction: 3.8 vs 2.6%,
p
= 0.002).
Conclusion
Pancreas fat is elevated in patients with BMI > 85% and in those with exocrine and endocrine insufficiencies.
