Differentiation of atypical hepatic hemangioma from liver metastases: Diagnostic performance of a novel type of color contrast enhanced ultrasound

Figure 2 color parametric imaging patterns of liver atypical hemangioma and liver metastases. First line was sketch figures for the four enhancement patterns of color parametric imaging. Second line was representative routine contrast-enhanced ultrasound images corresponding to the four enhancement patterns. Third line was representative color parametric images corresponding to the four patterns. A: Peripheral nodular enhancement; B: Peripheral rim-like with feeding artery (▲); C: Concentric circles enhancement; D: Mosaic enhancement with feeding artery (▲).
