Application of superb microvascular imaging in focal liver lesions

Figure 5 Diffuse honeycomb type (type IV). A-D: A 68-year-old male diagnosed with hepatic cellular carcinoma. A: A mixed-echo lesion with a relatively unclear margin was evident in the right liver lobe; B: SMI showed a diffuse honeycomb-distributed microvascular structure; C: Contrast-enhanced MRI showed diffuse enhancement of the lesion in the arterial phase; D: The pathology result showed that the inter-tumor blood vessels were distributed in a grid pattern resembling honeycombs. E-H: A 41-year-old male diagnosed with hepatic adenoma. E: A hypo-echo lesion with a clear margin was evident in the left liver lobe; F: SMI showed a diffuse honeycomb-distributed microvascular structure; G: Contrast-enhanced CT showed diffuse enhancement of the lesion in the arterial phase; H: The pathology result showed that the inter-tumor blood vessels were distributed in a grid pattern resembling honeycombs. SMI: Superb microvascular imaging.
