Research of MSCT scan postprocessing on Focal Nodular Hyperplasia / 中国基层医药

ABSTRACT

Objective To investigate and evaluate the pathological features and diagnostic significance of MSCT findings in scan postprocessing for focal nodular hyperplasia (FNH).Methods A total of 24 patients with FNH who underwent MSCT scan post processing were investigated.The FNH were pathologically and clinically confirmed.Results There are single focus in 22 cases and multiple focus in 2 cases.On plane scan 16 lesions were hypodensity and other 7 isodensity,4 hyperdensity( cases with fatty liver).After contrast,17 lesions were evenly high enhanced on arterial phase;13 lesions showed still hyperdensity and other 10 lesions isodensity,4 lesions hypodensity on parenchymatous phase.Only 5 lesions were hyperdensity but 9 lesions isodensity and 13 lesions hypodensity on delayed phase.Twelve lesions in 27 were detected with central stella-formed cicatrix.There were thickening tumor feeding arteries in 24 lesions,the artery of which were entered integrated into parenchymatous lesions with soft course.Conclusion Synthesizing the charcteristic appearance on MSCT scan postprocessing,doctor could make correct diagnosis and differentiated diagnosis for FNH.
