Generally, the most accurate examination of the pancreas is a CT scan.
CT scan is the preferred and most diagnostic imaging test in the diagnostic imaging of pancreatic lesions. It can not only diagnose acute pancreatitis, but also identify whether it is combined with pancreatic tissue necrosis. It can also provide a very important imaging basis for the qualitative and localization diagnosis of pancreatic tumors, especially in the preoperative assessment of the resectability of pancreatic tumors is of great significance.
As for MRI, MRI alone is not superior to CT, and it can provide similar diagnostic information to CT for pancreatitis. The detection rate of insulinoma is related to the size of the tumor, and the larger the tumor, the higher the diagnostic rate.
To summarize, CT is more advantageous for pancreatic examination.
