Venous Doppler findings are commonly detectable also in focal nodular hyperplasia with modern ultrasound equipments

Background: Previous studies showed that the presence of intratumoral vessels with a venous Doppler spectrum is often depicted in hepatocellular adenoma (HCA) but less in focal nodular hyperplasia (FNH). Based on this finding, Doppler imaging has been used for differential diagnosis between FNH and HCA with important consequences in the management of the two types of focal liver lesions. In particular, in some cases, the decision to perform liver resection in follow up patients with a subcapsular focal liver lesion of unclear interpretation between FNH or Adenoma at ce MR or ce CT, has been oriented versus adeno…
