Liver perfusion: FNH (focal nodular hyperplasia)
. Perfusion imaging of liver lesions, calculated from triphasic scans.
Focal nodular hyperplasia
Delayed enhancement of the central scar is shown in
on the color perfusion image. The apparent washout of the lesion in the
is an optical illusion due to the enhancing rim.
Hounsfield unit measurements
show that the lesion is isodense to liver on the delayed phase.
