The purpose is to investigate the efficacy of enhancement curve and parameters obtained from triple arterial and portal venous phase dynamic MRI of liver to differentiate malignant and hypervascular benign focal lesions. 35 HCCs and 16 hepatic hypervascular benign lesions were included. The analysis of phase-intensity curve and enhancement parameters showed that there are different MR dynamic enhancement patterns in HCCs and hypervascular benign focal lesions .The positive enhancement integral and maximum slope of increase of hepatic hypervascular benign focal lesions are higher than those of malignant ones, indicating different perfusion characteristics based on different pathologic architectures, which is helpful to differentiate these lesions.
