Pancreatitis is a relatively common acute abdominal disease in surgery. If patients with pancreatitis are considered to be suffering from this disease, the preferred imaging test is color ultrasound or CT. Color ultrasound can adequately visualize the enlargement of the pancreas, peripheral exudates, and dilatation of the pancreatic ducts. In the clinic, if the color ultrasound may be limited for people with heavy weight or obese body type, the imaging method of CT of pancreas can also be taken. CT of pancreas can fully visualize the overall size and shape of pancreas, as well as whether or not there are bile and pancreatic ducts stones and obstruction, which is very advantageous for diagnosing the pancreas. If the diagnosis of pancreas is relatively difficult, you can also do contrast or enhanced CT at the same time under the CT, which can thoroughly and effectively carry out the differential diagnosis, and it is a more ideal auxiliary imaging examination for the diagnosis of pancreatitis.
