核素^(99m)Tc标记红细胞扫描辅助诊断子宫内膜异位症的价值

The value of nuclide ^(99m)Tc-labeled red blood cell scintigraphy in auxiliary diagnosis of endometriosis

目的探讨核素99mTc标记红细胞扫描辅助诊断子宫内膜异位症的价值。方法选择28例有进行性痛经或性交痛等病史,妇科检查和B超均提示子宫内膜异位症患者,测定血清CA125水平。另选择门诊体检的正常人10例设为对照组。均于月经第1天或第2天预约99mTc标记红细胞显像,月经干净后来医院行腹腔镜手术及病理证实是子宫内膜异位症。结果核素99mTc标记的红细胞扫描的异位病灶大小明显小于B超的显影,且CA125>200U/ml比<200U/ml时显像更明显,出现时间更早。结论核素99mTc标记的红细胞扫描有助于早期辅助诊断子宫内膜异位症。

Objective To study the value of nuclide ^99mTc-labeled red blood cell scintigraphy in auxiliary diagnosis of endometriosis. Methods Twenty-eight patients with the history of advancing dysmennorrhea or algopareunia and the diagnosis of endometriosis indicated by gynecologic examination and uhrasonography were included in the study group, in whom CA125 was determined. Ten healthy people were chosen as the controls. The patients in both groups received ^99mTc-labeled red blood cell display on the first or the second day of the menstruation and endometriosis as confirmed pathologically. Results The size of ectopic focus found with nuclide ^99mTc-labeled red blood cell scin- tigraphy was much smaller than that with B uhrasonography,which was more and earlier with CA125 grater than 200 U/ml than that with CA125 less than 200 U/ml. Conclusion Nuclide ^99mTc-labeled red blood cell scintigraphy is helpful in auxiliary diagnosis of endometriosis at early stage.
