Tumor 10 - 20 mm in diameter	Hypervascular lesion confirmed in multiphase CT or DCE-MRI:      - Strong enhancement in hepatic arterial phase      - Wash-out in portal venous and/or equilibrium phases
Tumor larger than 20 mm	Hypervascular lesion confirmed in multiphase CT or DCE-MRI.

DCE-MRI – dynamic contrast-enhanced magnetic resonance imaging, CT – computed tomography.
