CT can detect pancreatitis, and it is important for patients to have a CT examination if they suspect pancreatitis. Because CT has a high diagnostic rate for pancreatitis, it can find out not only the severity of the swelling of the pancreas, but also whether there will be necrosis and infection inside the pancreas. Because of the seriousness of pancreatitis, and the rapid onset of pancreatitis, many patients have sudden pain in the upper abdomen or around the navel, and the nature of the pain is very intense, so it is possible that pancreatitis may not be detected during ultrasound examination, so it is recommended that patients should have a CT examination of the upper abdomen directly, combined with blood and urine amylase, blood lipase, as well as the results of routine blood and routine biochemical tests.
