Application of superb microvascular imaging in focal liver lesions

Figure 3 Strip rim type (type II). A-D: A 61-year-old male diagnosed with hemangioma. A: A high-echo lesion with a clear margin was evident in the left liver lobe; B: CDFI showed an interrupted strip blood flow signal around the edge of this lesion; C: SMI showed a relatively continuous strip rim-distributed microvascular structure; D: Contrast-enhanced CT showed strip rim enhancement of the lesion in the arterial phase. E-H: A 63-year-old male diagnosed with hemangioma. E: A low-echo lesion with a clear margin was evident in the left liver lobe; F: CDFI showed no blood flow signal for this lesion; G: SMI showed a continuous strip rim microvascular structure; H: Contrast-enhanced CT showed strip rim enhancement of the lesion in the arterial phase. SMI: Superb microvascular imaging.
