title: Hepatic focal nodular hyperplasia: findings on color Doppler ultrasound.
abstract: BACKGROUND
  We assessed the color Doppler ultrasound (US) findings in focal nodular hyperplasia (FNH).
  
  
  METHODS
  Seven FNH lesions were imaged with color Doppler US and hepatic angiography.
  
  
  RESULTS
  In four lesions, color Doppler demonstrated a central stellate vascular appearance which correlated with central feeding artery with spoke-wheel sign angiographically. Except for one lesion, color Doppler US imaging correlated with angiographic findings.
  
  
  CONCLUSIONS
  Color Doppler US is capable of demonstrating the typical findings of a central feeding artery and stellate vascular pattern in many cases of FNH.
