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

Figure 3 CE 3D US images of the liver in a 59-year-old woman with a hemangioma in the anterior inferior segment of the right lobe. A, B: Tomographic ultrasound image in plane A with slice distance 1.0 mm (A) and sonographic angiogram rendered by average intensity with surface mode (B) show peripheral nodular enhancement without distinct tumor vessels in the early phase; C: Tomographic ultrasound image in plane B with slice distance 1.0 mm shows peripheral nodular enhancement in the middle phase; D: Tomographic ultrasound image with slice distance 1.0 mm in plane B with slice distance 1.0 mm shows hypoechoic pattern in the late phase. Persistent enhancement over time was detected in this lesion. Arrowheads indicate the tumor margin.
