    Abstract:
    GOALS: To review magnetic resonance imaging and magnetic resonance cholangiopancreatography (MRCP) findings in patients with diabetes mellitus (DM), with pancreatic exocrine insufficiency, and with combined pancreatic exocrine insufficiency and DM. STUDY: MRI/MRCP findings of 82 consecutive patients with DM (n=28), pancreatic exocrine insufficiency (n=25), and combination of both (n=29) were evaluated and compared with MRI/MRCP findings of 21 healthy volunteers with normal pancreatic exocrine function. Pancreatic exocrine function was determined by fecal elastase 1. MRCP images were evaluated according to the Cambridge classification. MRI of the pancreas was assessed for pancreatic size, signal intensity ratio (SIR), and arterial/venous enhancement ratio (A/V). RESULTS: On MRI, significant difference was present in terms of mean values of pancreatic size (P<0.0001), A/V (P<0.02), and SIR (P<0.005) between the control group and groups of patients with DM, pancreatic exocrine insufficiency, and combined DM and pancreatic exocrine insufficiency. No significant difference was observed between groups of patients with DM and pancreatic exocrine function alone in terms of pancreatic size, A/V, and SIR. Chronic pancreatitis MRCP findings were present with increasing frequency in groups of DM, pancreatic exocrine insufficiency, and combination of both. CONCLUSIONS: MRI/MRCP findings suggesting chronic pancreatitis may exist in patients with DM comparable to patients with pancreatic exocrine insufficiency. The frequency and severity of MRI/MRCP findings increase when the patients have combined DM and pancreatic exocrine insufficiency.
