Differentiation of hepatocellular carcinoma from its various mimickers in liver magnetic resonance imaging: What are the tips when using hepatocyte-specific agents?

Figure 12 Angiomyolipoma in a 33-year-old woman. A: Hepatic arterial phase using gadoxetic acid shows heterogeneous arterial enhancement of the tumor. Early venous drainage to the right hepatic vein is seen (white arrow); B: Transitional phase shows heterogeneously low signal intensity; C: Hepatobiliary phase shows homogeneously low signal intensity; D, E: Opposed phase (D) and in-phase (E) T1-weighted gradient echo images reveal hypointense mass with area of signal drop on opposed-phase image (black arrows), indicating fat-containing lesion; F: T2-weighted image shows heterogeneous signal intensity of the tumor.
