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.
