Abstract：Objective To analyze the characteristics of MR examination in autoimmune pancreatitis, and to investi-gate the application value of MR in diagnosis and differential diagnosis of autoimmune pancreatitis.Methods Retrospectively analyzed the MR of 10 cases of autoimmune pancreatitis, all patients were underwent MR conventional plain scan, magnetic resonance cholangiopancreatography (MRCP), diffusion weighted imaging (DWI) and dynamic enhanced scanning.Results 7 cases of diffuse pancreatic involvement, 2 cases of pancreatic head limitations involvement, 1 case involved the body and tail of the pancreas.MR scan:T1WI showed equal or slightly low signal, T2WI showed slightly higher signal;MRCP:9 pa-tients with common bile duct stenosis, 8 cases of pancreatic duct diffuse or localized stenosis;DWI showed high signal, ADC showed low signal;dynamic enhanced scanning:lesions were not obviously enhanced in the arterial phase, venous phase and delayed phase revealed a homogeneous or heterogeneous delayed enhancement.6 patients with hormone therapy were followed up with MR, which indicates that the lesion volume was significantly reduced, the signal returned to normal.Conclusion Au-toimmune pancreatitis has character in each sequence of the MR, and MR is helpful for diagnosis of autoimmune pancreatitis and differential diagnosis with other pancreatic diseases.
