Contrast-Enhanced Ultrasound to Monitor Early Recurrence of Primary Hepatocellular Carcinoma after Curative Treatment

Figure 1

Results for a male patient, aged 46, in whom HCC recurred at 6 months after curative surgery. (a) Routine ultrasound showed hypoechoic nodules (1.8 × 1.5 cm) in the right anterior lobe near the secondary porta of liver. (b) Color Doppler flow imaging (CDFI) showed no color flow signal around or inside the nodule. (c) CEUS showed rapid, uniform enhancement in the arterial phase. (d) CEUS showed a low, rapidly decreasing enhancement in the portal phase. (e) CEUS showed low enhancement in the delayed phase. This CEUS expression pattern was “fast-in, fast-out”.
