Study on the value of radionuclide ~(99m)Tc labeled red blood cell scanning in diagnosis of endometriosis

Objective:To study the clinic value of diagnosing endometriosis with nuclide 99mTc-labeled red blood cell scan.Methods:From April 2005 to May 2006,22 patients were received and cured,who had advancing dysmennorrhea,clumps in one side of annexes by gynecologic examination and B ultrasonography.These patients were due to receive 99mTc-labeled red blood cell display in the first day or the second day of the menstruation and were given laparoscopic surgery after menstruation.Pathology confirmed chocolate cyst of ovary.Results:Ectopic focus founded with nuclide 99mTc-labeled red blood cell was much smaller than B ultrasonography.We found that when CA125200U/ml the display became more obvious and earlier than CA125200 U/ml.Conclusion:Nuclide 99mTc-labeled red blood cell scan is helpful in diagnosing endometriosis earlier,demonstrated earlier and has some value in clinic.
