How does fast in and fast out of liver cancer come from

summary

Many people don't know much about the fast in and fast out of liver cancer. At the beginning, I didn't understand what was going on. Since my father suffered from liver cancer, the doctor did an imaging scan for him. The doctor said it was the phenomenon of fast in and fast out. Many liver cancer patients still have doubts about this problem. Let me explain the fast in and fast out of liver cancer.

How does fast in and fast out of liver cancer come from

First of all, fast in and fast out is a kind of summary, which refers to the summary of imaging features generated by CT or MRI injection of contrast agent. It is determined by the pathological structure of liver cancer. There are two systems of blood supply in normal liver tissue, 75% of which come from portal vein system, and only about 25% from hepatic artery system; while more than 90% of blood supply in liver cancer comes from hepatic artery system.

Secondly, after the injection of contrast agent, the concentration of contrast agent in liver cancer tissue is significantly higher than that in normal liver tissue in a very short time. Imaging will show that the density or signal in liver cancer tissue is significantly enhanced, which is higher than that in normal liver tissue, which is manifested as filling in arterial phase. When the liver tissue obtains a large amount of contrast agent from portal vein system, the density or signal in liver cancer tissue will be increased The density or signal in the liver cancer tissue was significantly decreased, which was significantly lower than that in the normal liver tissue.

Finally, of course, there will be exceptions. For example, when the main nutrient vessels of the tumor and the portal vein system have a neoplastic arterioportal fistula, the performance of fast in and fast out is not obvious. For small hepatocellular carcinoma, especially those with little blood supply (such as hepatocarcinoma originated from bile duct cells), the expression of "fast in and fast out" is not obvious.

matters needing attention

Patients with liver cancer, especially in the late stage, due to the increasingly poor physique, they need to pay special attention to the food intake. Patients with advanced liver cancer should pay attention to the proper intake of fat and protein, eat more anti-cancer inorganic salt food, and supplement vitamins appropriately.
