Abstract:
Objective To investigate enhancement appearance of hepatic focal nodular hyperplasia(FNH) at real-time gray-scale contrast enhanced ultrasonography(CEUS),and evaluate the value of CEUS in the diagnosis of FNH. Methods Thirty-four patients (36 lesions) with histologically proved FNH were examined by ultrasonography. Appearance on conventional ultrasonography and the enhancement pattern on CEUS were investigated. Results Thirty-six lesions were mostly hypoechoic.39% (14/36) of lesions had peripheral hypoechogenic circle. Color Doppler flow imaging showed a asteroid-like or spoke-and-wheel pattern in 65% (20/ 31) of lesions.Three enhancement patterns were observed in the early arterial phase: whole-enhancement pattern (28%, 10/36), gushing-spring enhancement pattern (44%, 16/36), and spoke-and-wheel enhancement pattern (28%,10/36).The frequency of central scar on CEUS was 17% (6/36), and detection rate of central scar by CEUS compared with pathology was 40% (6/15).Regarding one of the features (gushing-spring enhancement, spoke-and-wheel enhancement and scar) as standard of FNH, the coincidence of CEUS in this group was 78% (28/ 36) ,which was significantly higher than that of conventional ultrasonography 28% (10/36).Conclusions CEUS can be as a important method for diagnosing FNH.
