Core Tip

Core Tip: Multifocal autoimmune pancreatitis is not as rare as previously thought and was seen in 22.0% of our patients. The diagnostic performance of diffusionweighted imaging for detecting multifocal autoimmune pancreatitis was best followed by axial fat-suppressed T1 weighted image and dynamic contrast enhanced-computed tomography.
