【Abstract】ObjectiveTo investigate the diagnostic value of the enhancement patterns for characterizing various focal hepatic lesions （FHL）.
MethodsForty-seven patients (50 lesions) were included into the study. The morphologic features and the dynamic enhancement patterns of FHL were observed in the early arterial phase, late arterial phase and portal venous phase.The degree of FHL enhancement was analyzed by calculating the contrasttonoise ratio.
Results70％ of the HCCs presented “fast-filling and rapid-washout” feature; 67％ of the cholangiocarcinomas showed slight enhancement in arterial phase, and 33.3％ had delayed enhancement on portal venous phase; All hemangiomas presented peripheral nodular enhancement in arterial phase, which then demonstrating centropedal “push-on” enhancement in portal venous phase; Hepatic abscesses mainly presented a slightly enhanced rim around the lesion with fibrous septa inside and an edematous zone outside.
ConclusionThe enhancement pattern and the dynamic evolution of FHL enhancement had a great diagnostic value for different FHL by using MRI 3D-VIBE sequence.
