Liver perfusion: FNH (focal nodular hyperplasia)
Figure 6. Perfusion imaging of liver lesions, calculated from triphasic scans.Focal nodular hyperplasia. Delayed enhancement of the central scar is shown in green on the color perfusion image. The apparent washout of the lesion in the delayed phase is an optical illusion due to the enhancing rim. Hounsfield unit measurements show that the lesion is isodense to liver on the delayed phase.
Other lesions:
A. Hepatocellular carcinoma
A. Hepatocellular carcinoma
B. Neuroendocrine tumor metastases
C. Focal nodular hyperplasia
D. Transient hepatic attenuation difference (THAD)
E. Giant hemangioma
