DEVELOPMENTAL STEPS FOR RADIONUCLIDE HYSTEROSALPINGOGRAPHY

The active oviductal transportation capacity was studied in 73 inferti le women by the use of a new deposition technique of radioactive parti cles into the internal cervical os. The main reason for this study was that a previous observation had shown that such a transportation capa city was lacking in 41 % of the infertile patients with a normal hyste rosalpingogram. The examination was performed in the immediate preovul atory phase, i.e. on days -3 to 0 before the ovulation, as measured by the basal body temperature during two preceding cycles. The depositio n of Tc-99m-labelled albumin particles of 0.2-1.0 mum at the internal cervical os and the interpretation of the radionuclide images are desc ribed in detail. The results show that the bilateral active tubal tran sportation capacity was present in 42 patients. An impaired transporta tion capacity was diagnosed in 22 patients. In 9 patients, the particl es never reached the uterine cavity, or all activity leaked back to th e vagina.
