Figure 2 Pancreatic magnetic resonance imaging findings. A: T1 weighted image; B: T2 weighted axial image; C: Diffusion weighted image; D: Vibe image; E and F: T2 weight coronal image; G: Magnetic resonance cholangiopancreatography. Magnetic resonance imaging showing a lesion in the ampulla of Vater with no clear T1 weighted and diffusion restriction image (A and C) but prominent enhancement, which is suspicious for ampulla of Vater cancer (B, D and E); magnetic resonance imaging showing main pancreatic duct upstream dilatation (F and G).
