Contrast-enhanced ultrasound: Improving the preoperative staging of hepatocellular carcinoma and guiding individual treatment

Figure 1 A 50-year-old man underwent right hepatic partial resection and left hepatic partial resection. A: CT just revealed the right HCC, not the left HCC which was identified by CEUS; B: Left HCC was discovered by conventional ultrasound; C-E: The left HCC was identified by CEUS in the arterial phase, portal phase and delayed phases; F: Right HCC identified by IOUS; G: Left HCC identified by IOUS. HCC: Hepatocellular carcinoma; CT: Computed tomography; CEUS: Contrast-enhanced ultrasound; IOUS: Intraoperative ultrasound.
