Effects of Gray-Scale Ultrasonography Immediate Post-Contrast on Characterization of Focal Liver Lesions
Figure 5
A 74-year-old man was found to have a liver tumor during the routine ultrasound examination. (a) US pre-CEUS showed an iso-echoic lesion with poor-defined margin in cirrhotic liver background. (b) US post-CEUS showed that the lesion had clearer border and a hypoechoic halo (ā) at 8 minutes after contrast agent injection. The CEUS pattern was atypical for this lesion. The diagnosis result of HCC was improved by US post-CEUS.
