目的　评价99Tcm 大颗粒聚合白蛋白 (MAA)输卵管显像在判断输卵管通畅及输卵管蠕动功能中的临床价值。方法　对 2 2 0例怀疑输卵管梗阻的原发性不孕症患者 ,经宫颈至宫腔注入99Tcm MAA 37MBq(1mL) ,分别于 90、180min进行盆腔前位平面显像 ,图像分析采用目测法。将梗阻分为 3组 ,第 1组为输卵管完全梗阻 ;第 2组输卵管不完全梗阻 ;第 3组输卵管通畅。第 1组患者显像后做输卵管通液试验。结果　第 1组有 79例患者 ,第 2组 10 8例 ,第 3组 33例。第 1组中有 6例输卵管通液试验显示通畅 ,提示其输卵管蠕动功能不良。结论　输卵管核素显像对输卵管梗阻的分类、其蠕动功能的判断和制定治疗方案具有重要的临床价值 Objective To evaluate the clinical value of 99Tcm MAA tubal imaging in judging tubal patency and tubal peristalsis. Methods Twenty-two patients with primary infertility suspected of fallopian tube obstruction were treated with 37 MBq of 99Tcm MAA (1 mL) through the cervix to the uterine cavity. The anterior pelvic imaging was performed at 90 and 180 min, respectively. Visual analysis was performed by image analysis. The obstruction was divided into 3 groups, the first group was tubal complete obstruction; the second group of tubal incomplete obstruction; the third group tubal patency. Group 1 patients after tubal fluid test done. Results There were 79 patients in group 1, 108 in group 2 and 33 in group 3. In group 1, 6 cases of tubal fluid-passing test showed patency, suggesting that tubal peristalsis dysfunction. Conclusions The classification of tubal obstruction by tubal radionuclide imaging has important clinical value in judging the peristaltic function and formulating the treatment plan
