^(99)Tc^m-MAA输卵管显像的临床应用

Clinical study of imaging of oviduct with ^(99)Tc^m-MAA

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。

Objective To evaluate the value of 99 Tc m MAA oviduct imaging in diagnosis and treatment in patients with infertility. Methods 220 patients with infertility underwent pelvis scanning at 90 min and 180 min after intrauterine injection of 99 Tc m MAA. The images were interpreted visually.The images of oviduct infarction were graded into 3 groups:the first group was infarcted entirely, the second group was infarcted partly,the third group was no infarction. Results There were 79 patients included in the first group, 108 patients in the second group,33 patients in the third group .The oviduct crawling function of 6 patients in first group was not good. Conclusion 99 Tc m MAA scintigraphy of oviduct is an effective technique for detecting oviduct infarction and its crawling function, and it would be very helpful to treatment programing.
