The role of contrast-enhanced ultrasound on the diagnosis of small hepatocellular carcinoma (≤3 cm) in patients with cirrhosis

The typical enhancement patterns of “FIFO” or “FISO” of small HCC could improve the diagnostic ability of ultrasound in cirrhotic liver. Small HCC also had atypical enhancement patterns including “FINO” and “SISO”. It shows that CEUS could be a useful imaging modality in small HCC diagnosis.
