Abstract

Pancreatic perivascular adipose tissue (PVAT) is a potentially important but understudied fat depot surrounding vessels supplying the pancreas, and its role in type 2 diabetes mellitus (T2DM) remains unclear. We aimed to quantify pancreatic PVAT automatically on routine abdominal computed tomography (CT) scans and assess whether PVAT-derived imaging biomarkers are associated with T2DM and future T2DM risk. PVAT biomarkers were associated with T2DM and were informative predictors in multivariable models. Exploratory analyses showed similar findings for incident T2DM (disease onset within 4 years of follow-up). PVAT may represent a novel CT-based biomarker for early metabolic dysfunction and T2DM risk stratification.
