摘　　要：本文对52例经B 超、CT 和AFP 检查的原发性肝癌患者进行回顾性研究。B 超检测小肝癌(<3cm)75%呈低回声圆形病灶,随着肿瘤体积的增大,由低回声变为等回声和强回声。小肝癌阶段其直径每增大1cm 约需3～4个月。B 超诊断符合率为92.30%(48/52)。本组肝癌的CT 图像均呈低密度病灶,<3cm 的病灶大多呈圆形,边缘整齐。CT 诊断符合率为96.15%(50/52)。血AFP>400μg/L占50%。对慢性肝病患者应每3～4个月查一次B 超和AFP 以提高小肝癌的检出率。Ultrasonography,CT and a-fetoprotein(AFP)were reviewed in 52 patientswith primary hepatic cancer retro-spectively.Sonographically the small liver cancer(<3cm)appeared as well defined hypoechoic lesion that changed to a isoechoic andhyperechoic lesion as the tumor increased.An increase in 1cm of diameter in the stage ofthe small liver cancer needed about 3-4 months.The accurate rate of the PHC in sonogra-phic diagnosis was 92.3%(48/52).CT showed the low density of all lesions.The lesions<3cm showed in round shape.The accurate rate of the PHC in CT diagnosis was96.15%(50/52).The serum AFP 400μg/L was 50%(26/52).It is proposed that patients withchronic liver disease should be examined by sonography and AFP every 3-4 month so thatthe detection rate of the small liver cancer in early stage can be increased.
