Differentiation of focal liver lesions using three-dimensional ultrasonography: Retrospective and prospective studies

Figure 4 CE 3D US images of the liver in a 77-year-old man with FNH in the medial segment of the left lobe. A-C: TUI in plane A with slice distance 1.5 mm (A) and plane B with slice distance 1.5 mm (B), and the sonographic angiogram rendered by maximum intensity with surface mode (C) show diffuse enhancement with spoke-wheel arteries (arrows) in the early phase; D: TUI in plane C with slice distance 2.5 mm show isoechoic pattern in the late phase and hypoechoic regions within the tumor indicate central scars. Persistent enhancement over time was detected in this lesion. Arrowheads indicate the tumor margin.
