Fig. 1B. —68-year-old woman with flash-filling hemangioma that was prospectively detected on helical CT as hepatocellular carcinoma. Helical CT image obtained at same level as A during portal venous phase shows that lesion (arrowhead) has decreased its enhancement slightly but remains enhanced to similar degree as blood pool seen in vessels. In retrospect, hepatocellular carcinoma would not remain as blood pool attenuation but would exhibit washout phenomena either isoattenuating or hypoattenuating to surrounding liver. Unenhanced CT scan (not shown) also showed lesion to be isoattenuating with blood vessels.
