Longitudinal Magnetic Resonance Imaging (MRI) Shows Progressive Decline in Pancreas Size and Altered Pancreas Shape in Type 1 Diabetes

J Clin Endocrinol MetabPublished Prospective cohort study

Authors' conclusion

Pancreas size declines most rapidly near the clinical diagnosis of T1D and continues to decline throughout adulthood. Declines in pancreas size are accompanied by changes in pancreas shape.

Study context

Population
Individuals with T1D and controls undergoing pancreas MRI, academic medical center, 2014–202253 with longitudinal MRI
Participants
91 vs 90
Exposure
T1D vs controls
  • T1Dn = 91
  • Controlsn = 90reference
Outcome
Pancreas size and shape measured from MRI
Methodological detailssingle academic medical center, longitudinal MRI, cross-sectional analysis
  • Single academic medical center
  • Longitudinal MRI
  • Cross-sectional analysis

Main finding

As reported in the abstract

  • Pancreas volume and pancreas volume index normalized for body weight declined during the first year after diagnosis
  • Pancreas volume index continued to decline through the fifth year after diagnosis
  • Pancreas shape altered in T1D and further diverged from controls over the first 5 years after diagnosis

Observational data: associations, not effects.

Further findings

Cross-sectional pancreas size (diabetes duration up to 60 years)

Pancreas size in adults with T1D negatively correlated with age and disease duration; pancreas volume and volume index stable in controls

Pancreas volume index and glycemic variability

Pancreas volume index correlated inversely with low blood glucose index (hypoglycemia risk)

Nondiabetic individuals at genetic risk for T1D

Pancreas size and shape altered

Discrimination of T1D from controls

Combined size and shape analysis better distinguished T1D from controls than size alone
