What are the preliminary examination items for pancreatic cancer

Nowadays, pancreatic cancer has become very common. Surveys show that many patients fail to detect the disease in time, mainly because they ignore pancreatic cancer examinations. Pancreatic cancer examinations are very important for disease diagnosis and treatment. I hope everyone will pay attention to it. Let's take a closer look.

First, B-ultrasound. Direct images of pancreatic cancer can show low-echo tumors, and indirect findings often become clues to discover small pancreatic cancers, such as dilated pancreatic ducts and bile ducts. In addition to the main pancreatic duct, the branches of the pancreatic duct should also be carefully observed. Some small pancreatic cancers may first cause localized dilation of the pancreatic duct branches, such as dilation of the uncinate process pancreatic duct.

Second, CT scan. CT scan can show the correct location and size of pancreatic masses and their relationship with surrounding blood vessels, but about 1/3 of pancreatic masses <2 cm cannot be found in imaging changes, in addition to the high cost. CT scan should be listed as the main method for diagnosing pancreatic cancer.

Third, magnetic resonance imaging (MRI). MRI can show abnormal pancreatic contours. Based on the signal level of T1-weighted images, early local invasion and metastasis can be determined. MRI is superior to CT scans in determining pancreatic cancer, especially small pancreatic cancer confined to the pancreas, and whether there is peripancreatic spread and vascular invasion. It is a good method for predicting pancreatic cancer before surgery, but it is expensive.
