For the hepatocellular carcinomas, the presence of small satellite lesions is an important determinant of a patients prognosis and therapeutic planning. Through the results of our study DWI is superior to dynamic MRI in the detection and characterization of subcentimeter lesions and can be added to strengthen the accuracy in the MRI assessment of intrahepatic metastases of HCCs. DWI could overcome the inherent drawbacks of dynamic MRI for the hypervascular pseudolesions or obscured tumoral vascularities by the perfusional changes in the background parenchyma serve as a complementary tool for patients examined by dynamic MRI.
