The distributions of the superb microvascular imaging types between the most common malignant focal liver lesions (hepatocellular carcinoma and metastatic lesions ) and the most common benign focal liver lesions (hemangiomas) were significantly different (P = 0.048, < 0.05). Type I: Diffuse dot-like type; Type II: Strip rim type; Type III: Nodular rim type; Type IV: Diffuse honeycomb type; Type V: Non-specific type; Type VI: Thick rim type; Type VII: Spoke-wheel type; HE: Hemangioma; M: Metastatic lesion; HCC: Hepatocellular carcinoma; FNH: Focal nodular hyperplasia; HA: Hepatic adenoma; PHL: Primary hepatic lymphoma.
