Multicenter Assessment of the Pancreas in Type 1 Diabetes

Overview

The overall goal of this research is to develop and validate standard operating procedures (SOP) to assess the human pancreas in individuals with type 1 diabetes (T1D) and other forms of diabetes using advanced, quantitative magnetic resonance imaging (MRI) approaches.

This research applies magnetic resonance imaging (MRI) techniques to study the pancreas of individuals with type 1 diabetes (T1D) and other forms of diabetes. Recent studies have demonstrated reduced pancreatic volume is present within months of T1D diagnosis in children, adolescents, and adults, and in non-diabetic individuals expressing islet autoantibodies that portend the development of T1D. As the pancreatic beta cells constitute only 1-2% of the pancreas, the degree of reduction in pancreas volume at disease onset suggests exocrine involvement, challenging the established paradigm of T1D being solely a disease of the endocrine pancreas. These unexpected findings raise fundamental questions that challenge our understanding of T1D pathogenesis. These changes in pancreatic volume and size before and soon after onset of T1D, as detected by MRI, appear to be a marker of the T1D pathogenic disease process. There is an urgent need to determine whether similar observations can be obtained at different centers using different MRI platforms. Discovery of unknown changes may lead to new ways to treat disease. The MRI techniques may also be useful for following how T1D is progressing in different people, determining whether new drugs are effective, and ultimately detecting T1D in people earlier than currently possible.
