Abstract:
Objective To evaluate the value of the ultrasound and the helical CT in the diagnosis of hepatic focal nodular hyperplasia(FNH).Methods Fifteen patients with 16 lesions were examined by B-mode ultrasound ,color Doppler ultrasound and helical CT. All of them were proved to be FNH by pathology.Results In these patients, the hypoechoic pattern with homogeneous solid lesions was mostly displayed on B-mode ultrasound, and the central stellate scar was only found in 1 lesion. A color blood flow with arterial spectrum was detected within central area of FNH in 13 lesions, and spokewheel color flow was depicted in 3 lesions. These color flow patterns were specific for FNH. All lesions were hypervascular and homogeneous on arterial phase scans of CT. The central scars were detected in 7 lesions, and a dilated feeding artery was seen in 8 lesions on the arterial phase scans. The isodense changes were displayed in 11 lesions on the portal phase or delayed phase.Conclusions The conventional ultrasound combined with color Doppler ultrasound and CT combined with dynamic scan can raise the accuracy for the diagnosis of FNH.
