【摘要】 用¹³¹I-CEA McAb放射免疫显像诊断10例卵巢癌患者,使用γ-闪烁显像辅以微机图像处理技术和双核素减影术获得较好效果。10例全部阳性显像,与手术及病理结果完全相符,卵巢癌RII分期与手术分期亦完全符合。31处转移灶发现30处,阳性率97%,最小检出病灶直径1.5cm。本法在对病灶进行定性诊断同时可直接显示病灶位置、形态、大小及数量。对早期发现、指导临床分期、估计预后有较高的临床价值。更多还原

【Abstract】 Ten cases of ovarian cancers have been detected with I 131 labelled CEA McAb and computer assisted clual radionuclide subtraction tech-nique.The lesions(both primary and secondary)are clearly visualized andproved by surgical and pathohistological findings.30 of 31 metastatic lesionsare localized with a positive rate 97%.It seems to be a sensitive andspecific procedure for early diagnosis of ovarian cancer so far.It is alsovaluable for staging clinical course and making decision on treatment,assessing the prognosis of ovarian cancer as well.更多还原
