摘要
报道原发性肝癌36例及肝良性占位病变17例的彩色多普勒超声显象及脉冲多普勒超声测定结果。原发性肝癌94.4％显示病灶周边弧形彩色血流包绕征,83.3％显示病变内部片状或条索状彩色血流及肝内动脉扩张,流速加快。脉冲多普勒见异常血流以脉冲型为主,良性病变无以上特点。故彩色多普勒显象对肝内占位性病变良、恶性的鉴别诊断有重要价值。
36 cases of primary liver cancer and 17 cases of benign spaceoccupying lesions were studied with color Doppler flow imaging (CDFI) and ultrasonic pulsed Doppler. Among the 36 cases of primary hepatic carcinoma, abnormal color blood flow around tumor nodules was observed in 34 cases (94.4%), and blood flow within the tumors was seen in 30(83.3%). When the blood flow was demonstrated, it showed a pulsating wave pattern in all cases. The blood flow within the tumors also showed a pulsating wave pattern in all but one. These characteristics were found in most of the primary hepatic carcinomas but not in benign space-occupying lesions. So color Doppler flow imaging is useful in the differential diagnosis of hepatic tumors.
