Abstract:
Objective To explore the correlation between the enhancement pattern of hepatocellular carcinoma (HCC) on contrast-enhanced ultrasound (CEUS) and its tumor differentiation on histopathology. Methods HCC lesions (n=259) from 224 patients were retrospectively evaluated with CEUS and histopathological examination. CEUS was performed with SonoVue. The characteristics of blood perfusion and parameters of the time-intensity curve (TIC) were analyzed by ACQ soft?ware. Histopathological diagnoses were decided base on Edmonson grading system. Results Pathologic grading of HCC was not related to the arrival time(P>0.05);The washing-out time point and the enhancement time point and peak time point all appeared earlier in poorly differentiated HCC group, than those in moderately differentiated HCC group than those in well differentiated HCC group(P<0.01);The enhancement time point and the expurgation time point are shorter in poorly differ?entiated HCC group than those in moderately differentiated HCC group than those in well differentiated HCC group. All dif?ferences were with statistical significance. The mode of arterial perfusion in early stage was divided into 3 types:spider web type, radiative type and mixed type. The well differentiated HCC group mainly presented as radiative type ( 28/49, 47.14%). But the most of poorly differentiated HCC group mainly present as spider web type(88/127, 69.29%). The mix type was more common in moderately differentiated HCC group(49/83, 59.03%). Conclusion CEUS show different features of TIC pa?rameters and blood perfusion in different pathological stages of HCC lesions so it can serve as a method to assess the biologi?cal behavior of hepatocellular carcinoma.
