Hepatic malignancies: Correlation between sonographic findings and pathological features

Figure 3 Advanced hepatocellular carcinoma. A: The nodule had a halo image and mosaic pattern in segment 8 of the liver on B-mode ultrasonography; B: Power Doppler imaging showed hypervascularity of the tumor; C: Color Doppler imaging showed intratumoral blood flow. Arterial pulsatile waveforms could be detected by pulsed Doppler images; D: The image of a simple nodular type with extranodular growth (arrow) was obtained on B-mode ultrasonography (US); E: Contrast harmonic US showed enhancement of hepatocellular carcinoma in early vascular phase after administration of perfluorocarbon microbubbles; F: Contrast harmonic US depicted the defect image in the post-vascular phase.
