Application and progress of medical imaging in total mesopancreas excision for pancreatic head carcinoma

Figure 4 Typical magnetic resonance features of pancreatic head carcinoma in a 57-year-old female patient. A–C: Swollen pancreatic head (arrow) with slightly higher signal on T2-weighted imaging (WI) (A) and diffusion-weighted imaging (B), and low signal on T1WI (C) was detected; D: Notes that the dilation of pancreatic duct (arow head) and double duct sign on magnetic resonance cholangiopancreatography; E–H: After administration of contrast agent, the tumor shows a progressive enhancement pattern similar to computed tomography on early arterial phase (E), late arterial phase (F), venous phase (G), and delay phase (H).
