Restricted liver DWI diffusion is considered to be related to diseases such as liver abscess, liver cyst, liver cancer, etc. It is necessary to go to the hospital for further examination to clarify the cause of the disease and then consult the doctor in time. 1. Liver abscess: It is usually due to the fact that liver abscess will secrete abscess with high viscosity and purulent material, thus the phenomenon of liver DWI diffusion limitation occurs, and liver abscess may present with symptoms such as pain and respiratory difficulty. 2. Liver cysts: usually due to the fact that liver cysts will cause the water molecules of liver lesion tissues to be restricted in diffusion, causing the phenomenon of liver DWI diffusion limitation, and liver cysts may have symptoms such as liver enlargement and right upper abdominal discomfort. 3. Liver cancer: it may be due to the cancer cells in liver cancer, which stimulate the liver to damage the liver, thus resulting in restricted diffusion of water molecules, causing restricted diffusion of liver DWI. Liver cancer in advanced stage may also have symptoms such as pain and abdominal distension. If the phenomenon of limited diffusion of liver DWI occurs, one should go to the hospital for consultation in time to avoid delaying the condition. In daily life, one should pay attention to rest, reasonable diet and balanced nutrition.
