Abstract:
Objective To study the significance and value of imaging typing by analyzing the correlation between contrast-enhanced ultrasound perfusion imaging typing and vascularization in patients with primary hepatocellular cancer.Methods The early enhanced arterial phase reflecting angioarchitecture,and the size and edge of enhanced tumor closely related to microvessel distribution, position and density, were observed and analyzed in 89 patients (113 lesions).All the cases were pathologically proved, and some received immunohistochemisty staining and the microvessel density were recorded.Results The perfusion imagings were classified into 4 types according to changes on contrast-enhanced ultrasound,dendritic,mixed,circular and net-like type.Atypia vessels were commonly seen in dendritic type,and Ⅲ and Ⅳ accounted for 79.1%.The microvessel density was higher than the other types.The circular type was relatively regular and Ⅲ and Ⅳ accounted for 12.5%.The microvessel density was lower than the other types.Combined with the contrast-enhanced ultrasound perfusion imaging and compared with pathological grading,growing methods and microvessel density, the dendritic type was characterized by infiltrative growth, and had strong invasion tendency.The circular type was characterized by expansive growth.And the other two types were characterized by transitional type.Conclusions Contrast-enhanced ultrasound can reflect the angioarchiteeture, the microvessel density and the position,and it is related to the pathological grading and growing methods.
