- W2348852110 abstract "Objective:To study the CT and MRI features and the optimal protocol of multi-phase enhanced CT of normal pig's pancreas and compare them with human beings.Methods:CT plain scanning and thin-slice dynamic enhanced scanning were performed respectively in 10 healthy pigs.Six of them underwent MRI at the same time,including T1WI,T2WI,DWI and MRCP sequences.All of the pigs were cuted to observe pig pancreas shape and position with naked eyes.The CT and MRI findings were compared with surgery.Results:①The pancreas of pig which liked clover was divided into three parts,pancreas head,left lobe and right lobe.The left lobe was the main part of pig's pancreas.It was resemble considerably to human being' pancreas,such as dissection location,general morphologic,the per-pancreatic vessels,CT density,MRI signals of T1WI、T2WI and diffusion-weighted imaging(DWI) and ADC value;②The images of pancreasticobiliary of normal pigs on MRCP were different from those of human being.It's bile duct and pancreatic duct converged at the duodenum respectively.The bile duct was comparatively wider with diameter of 5～6 mm,while the pancreatic duct was narrow with diameter of 1～1.5 mm and it was difficult to be shown by MRCP;③ Multi-phase enhanced CT protocol: the results of enhanced CT scanning indicated that the time-density curve was similar with that of human beings.The optimal scanning protocol was: 15 s for arterial phase,35s for the pancreatic parenchyma,45 s for the peripancreatic portal vein phase.Conclusion:The CT and MRI features and multi-phase enhanced CT scanning protocols of pancreas of pigs are considerable similar with that of human beings.Therefore,the pig may be an ideal model of big animal in imaging research of pancreas diseases." @default.
