Patterns of CEUS of focal liver lesions [3]

Lesion	Arterial phase (up to 45 s)	Portal phase (45–120 s)	Late venous phase (Beyond 120 s)
Simple cyst	Non-enhancing	Non-enhancing	Non-enhancing
Hemangioma	Peripheral enhancement	Centripetal filling or peripheral globular enhancement	Hyper-enhancement
Focal nodular hyperplasia	Central enhancement	Hyper-enhancement with central scar	Iso-/hyper-enhancement
Hepatic adenoma	Variable enhancement	Variable enhancement	Variable vs. hypo-enhancement
Hepatocellular carcinoma	Hyper-enhancement	Iso-/non-enhancement	Hypo-/non-enhancement
Cholangiocarcinoma	Rim enhancement	Hypo-enhancement	Non-enhancement
Metastatic lesion	Rapid hyper-enhancement (hyper-vascular) or rim enhancement (hypo-vascular)	Iso-/non-enhancement	Hypo-/non-enhancement
