What are the diagnostic methods for pancreatic cancer?

Pancreatic cancer is a disease that makes everyone tremble all over, because this disease is still very harmful to people, so it is recommended that you first diagnose the disease before you can treat it symptomatically. You must go to a regular hospital, otherwise you will bear the consequences yourself! Because your body is your own, you must be cautious!

(I) 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 scan 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. However, it is expensive.

(II) Laboratory examination showed that serum bilirubin was significantly elevated, sometimes exceeding 342μmol/L, with direct bilirubin being the main elevated level. Blood alkaline phosphatase was also significantly elevated. Urine bilirubin test was positive or strongly positive. Blood amylase was transiently elevated in a few early pancreatic cancer cases due to pancreatic duct obstruction; in the later stages of pancreatic tissue atrophy, blood amylase values ​​would not change.

(III) CT scan CT scan can show the correct location, size and relationship of pancreatic masses with surrounding blood vessels, but about 1/3 of pancreatic masses <2 cm cannot be found in imaging changes, except for the high cost. CT scan should be listed as the main method for diagnosing pancreatic cancer. The CT images of pancreatic cancer are: ①. Pancreatic masses are generalized or localized. There may be an irregular low-density area with blurred outlines in the center of the mass. If the low-density area is large, it may be a manifestation of tumor necrosis or liquefaction; ②. When the cancer invades or compresses the bile duct or pancreatic duct, it can cause it to expand; ③. The cancer can invade the dorsal fat layer of the pancreas and surround the superior mesenteric vessels or the inferior vena cava.

(IV) Direct images of pancreatic cancer by B-ultrasound can reveal low-echo tumors, and indirect findings often become clues for discovering 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 pancreatic duct. Because the ultrasound probe of endoscopic ultrasound only scans the pancreatic body, tail and head through the stomach and duodenal walls, it is not affected by gastrointestinal gas. Therefore, the pancreatic structure can be clearly depicted and early lesions can be discovered.

In summary, we have explained the diagnosis method of pancreatic cancer. This disease should not be ignored. If you do not treat it in time, the condition may become more and more serious. If it causes other complications, it may endanger your life. Therefore, you must avoid the deterioration of the disease and must treat it seriously and in time!
