Application of superb microvascular imaging in focal liver lesions

Figure 7 Thick rim type (type VI) in a 71-year-old male diagnosed with primary hepatic lymphoma. A: A low-echo lesion with a relatively clear margin was evident in the left liver lobe; B: SMI showed a thick rim-distributed microvascular structure; C: Contrast-enhanced ultrasound showed thick rim enhancement of the lesion in the arterial phase; D: The gross pathology result showed a thick rim distribution of the vasculature. SMI: Superb microvascular imaging.
