Hepatocellular carcinoma in a 45-year-old woman with underlying liver cirrhosis. A: T2-weighted magnetic resonance image shows a high signal intensity hepatocellular carcinoma (HCC) in segment 4 of the liver (arrow); B: On a B-mode image, the HCC is seen as an ovoid, hypoechoic mass (arrow), that appears darker (stiffer) than hepatic background on the acoustic radiation force impulse image (arrow). The shear wave velocity of HCC and surrounding hepatic parenchyma were measured as 2.20 m/s and 1.57 m/s, respectively (not shown).
