CT of invasive liver cancer mainly looks at the size, shape, margins and density of the lesion as well as to see whether there is enhancement.
Invasive hepatocellular carcinoma is also called diffuse hepatocellular carcinoma, which has small diffuse nodules distributed throughout the liver with unclear borders. The nodules are usually smaller than 3 cm and appear as low-density lesions.
When enhancement scan is performed, there is no obvious enhancement of liver parenchyma in arterial stage, and the hepatocellular carcinoma foci show patchy enhancement. In the portal vein stage, the portal vein and liver parenchyma are obviously strengthened, and the strengthening of the tumor decreases rapidly. In the equilibrium phase, the liver parenchyma strengthens and the tumor is relatively hypointense.
Imaging plays an important role in liver cancer screening. Early detection of invasive hepatocellular carcinoma can be effectively treated and has a better prognosis, but once it develops into middle or late stage, the prognosis is worse. Physical examination should be conducted regularly for early detection and treatment. Once you feel sick, you should go to the hospital for treatment as soon as possible to avoid delaying your condition.
