摘要
目的:研究二维及三维超声在肝内小血管瘤与肝癌鉴别诊断中的作用。方法:选择经手术病理证实、肝组织病理活检或增强CT/MRI检查最长径<3cm的肝内小占位性病变,66例共87个病灶;其中肝小血管瘤26例33个病灶,小肝癌40例54个病灶(原发性肝癌27例27个病灶、肝转移癌13例27个病灶)患者,行二维及三维超声检查。分别记录PSV、RI、VI。结果:典型的小肝癌及肝小血管瘤二维图像有特征性的改变,血流速度小肝癌高于肝小血管瘤,三维超声的血流指数原发性和转移性小肝癌均高于肝小血管瘤,但原发性和转移性小肝癌之间的血流指数无差异。结论:三维超声可以定量研究肝脏小占位性病变的血流指数,肝小血管瘤及小肝癌的血流指数特点在协助二维及彩色多普勒超声鉴别诊断方面有一定的作用,二维和三维相结合可以更好地定性诊断肝内小病变。
Objective：The p~ of the study was to investigate the value of two-and three-dimensional ultrasund in differential diag- nosis of small hepatic hemangioma and small hepatic carcinoma.Methods：The small lesions whose the largest diameter was less than 3.0 cm were selected in the study. All the lesions were confirmed by either pathology after operation, biopsy or enhanced CT/MRI. These eighty-seven lesions included thirty-three small hepatic hemangioma in twenty-six patients and fifty-four lesions in fourty patients （twenty- seven primary hepatic carcinoma in twenty-seven patients and twenty-seven hepatic metastatic carcinoma in thirteen patients）. All the pa- tiems were examied by two-and three-dimensional ultrasound. The PSV, RI and VI were recorded.Results：Representative small hepatic hemangioma and small hepatic carcinoma had characteristic change on gray scale image. The flow velocity of small hepatic careinama was higher than that of small hemangiama. The VI of either primary hepatic carcinoma or hapatic metastatic eareinoma measured by three-di- mertsiunal ultrasound was higher than that of small hepatic hemangioma respectively. And the values of VI between primary hepatic carci- noma and hapatic metastatic carcinoma were not statistic difference. Conclusion： The VI of small lesions can be investigated by three-di- mensional ultrasound. The characteristic of small hepatic hemangioma and small hepatic tumor can be used for differential diagnosis them- selves. The small lesions of liver can be diagnosed qualitively by both the feture of two-and three-dimensional ultrasound.
