  		Figure 1. Hepatocellular carcinoma(HCC) (Edmonson grade I) in a 65-year-old man. (a) Baseline ultrasound image shows a hypoechoic HCC nodule in the right lobe of the liver 2.1 cm in diameter. (b) Arterial phase image obtained at 19 s after contrast agent administration shows a homogeneous hyperenhancement of the lesion. (c) Portal phase image obtained at 82 s. The nodule is isoechoic with respect to the surrounding liver. (d) Late portal phase image obtained at 190 s. The HCC is slightly hypoechoic with respect to the surrounding liver.

  		Figure 2. Hepatocellular carcinoma(HCC) (Edmonson Grade II) in a 46 year old man. (a) Baseline ultrasound image shows an isoechoic HCC nodule in the right lobe of the liver 3.3 cm in diameter. (b) Arterial phase image obtained at 16 s after contrast agent administration shows a homogeneous hyperenhancement of the lesion. (c) Portal phase image obtained at 113 s. The nodule is slightly hypoechoic with respect to the surrounding liver. (d) Late portal phase image obtained at 240 s. The HCC is hypoechoic with respect to the surrounding liver.

  		Figure 3. Hepatocellular carcinoma(HCC) (Edmonson grade III) in a 51-year-old man. (a) Baseline ultrasound image shows a hypoechoic HCC nodule in the right lobe of the liver 2.0 cm in diameter. (b) Arterial phase image obtained 23 s after contrast agent administration shows a homogeneous hyperenhancement of the lesion. (c) Portal phase image obtained at 48 s. The nodule is slightly hypoechoic with respect to the surrounding liver. (d) Late portal phase image obtained at 180 s. The HCC is hypoechoic with respect to the surrounding liver.

  		Figure 4. Hepatocellular carcinoma(HCC) (Edmonson grade IV) in a 60-year-old woman. (a) Arterial phase image obtained 18 s after contrast agent administration shows a heterogeneous hyperenhancement of the lesion. (b) Portal phase image obtained at 32 s. The nodule is slightly hypoechoic with respect to the surrounding liver. (c) Portal phase image obtained at 90 s. The nodule is hypoechoic with respect to the surrounding liver. (d) Late portal phase image obtained at 180 s. The nodule is remarkably hypoechoic with respect to the surrounding liver.

  		Figure 5. Hepatocellular carcinoma(HCC) (Edmonson grade I) in a 67-year-old man. (a) Baseline ultrasound image shows a hypoechoic HCC nodule in the right lobe of the liver 2.3 cm in diameter. (b) Arterial phase image obtained at 23 s after contrast agent administration shows a homogeneous isoenhancement of the lesion. (c) Portal phase image obtained at 52 s. The nodule is isoechoic with respect to the surrounding liver. (d) Late portal phase image obtained at 280 s. The HCC is isoechoic with respect to the surrounding liver.
