Figure 4

Ultrasound scans in a 54-year-old male with moderately differentiated hepatocellular carcinoma (HCC). (a) Greyscale sonography image showing a hypo-echoic nodule 3.9 cm in diameter. (b) Arterial phase scan at 16 s showing markedly hypervascular nodule (arrows). (c) Portal phase scan at 60 s showing hypoenhancement (arrows) compared with parenchyma. (d) Late phase scan at 140 s showed hypo-enhancement (arrows). (e) Output time–intensity curves of HCC (in green) and reference (in yellow) showing that washout time (WT) in the moderately differentiated HCC was medium (WT=20 s).
