Fig. 3. Multiphase contrast-enhanced CT in a 55 year-old woman with cirrhosis.

Fig. 3.

(A) the lesion in the right posterior hepatic lobe is not visualized on the unenhanced CT image. (B) axial CT image obtained in the arterial phase demonstrates an arterially-enhancing lesion (white arrow), raising concern for HCC. (C) the lesion become isoenhancing in the portal venous phase without clear washout (white arrow). (D) axial CT image in the 3-m delayed phase demonstrates clear washout and clinches the diagnosis of HCC. If the examination was terminated prior to obtaining the delayed phase, the diagnosis of HCC could not be made.
