Fig. 1B —Criteria for visual diagnosis of solid liver tumors after microbubble contrast agent injection. Higher, similar, or lower in echogenicity compared with adjacent liver was assessed, respectively, as hypervascular (subjective conspicuity = 1 or 2), isovascular (subjective conspicuity = 0), or hypovascular (subjective conspicuity = -2 or -1). Criteria used for visual diagnosis of benignancy: Diffuse indicates that enhancement of whole lesion was homogeneous or heterogeneous; peripheral nodular, discontinuous or continuous peripheral enhancement with nodular appearance; central spoke-wheel-shaped, enhancing central vessel appeared to branch toward the periphery of the lesion; and absent, no difference before and after microbubble injection, with persistent hypovascular appearance.
