Hepatocellular carcinoma (HCC) with same color and worse conspicuity on conspicuity on acoustic radiation force impulse (ARFI) 2-dimensional (2D) image of 69-year-old male with chronic liver disease.

A, B. This HCC shows same stiffness as adjacent chronic liver disease parenchyma on ARFI 2D image. Conspicuity of this hypoechoic HCC is worse on ARFI 2D image. C, D. Median shear wave velocity (SWV) of this HCC and hepatic parenchyma was 1.90 m/sec and 2.39 m/sec, and SWV difference was -0.49 m/sec. Scales provided by dots in right vertical axis of B-mode images are in centimeters.
