Color Doppler
Color Doppler US may demonstrate peripheral peritumoral vessels and intratumoral vessels that typically have a flat continuous or, less commonly, triphasic waveform. *These Doppler US features are reported to be absent in the vessels within focal nodular hyperplasia and may be useful in distinguishing the two disease entities. *Nevertheless, most adenomas are not specifically diagnosed at US and are usually further evaluated with CT or other imaging modalities.
