    Abstract:
    A prospective study in 38 patients was designed to evaluate the efficacy and reliability of radionuclide hysterosalpingoscintigraphy (HSS) using 99mTc labelled human albumin macroaggregates (HAMA). Following application in the posterior vaginal fornix at the time of ovulation, HAMA normally migrate spontaneously through the uterus and tubes and may be identified after 20 min (range 5-90 min) in the uterine cavity and after 2 hrs (range 40 min - 3 hrs) in the free pelvis, using a gamma camera. When correlated with the findings of conventional contrast hysterosalpingography (HSG), the radionuclide procedure yielded comparable results in females with patent or clearly obstructed tubes. Using 8-10 MBq 99mTc, radiation exposure was estimated to be 0.75 cGy per ovary, which is considerably less than the mean dose absorbed with HSG. As the HSS procedure imitates the migration of spermatozoa by the means of an inert tracer, it allows a direct insight in the mechanisms of passive transport taking place in the uterus and tubes at the period of ovulation. Thus, it reflects the physiological state of the female reproductive tract. On the basis of the scintigraphic findings, equivocal results on HSG have to be re-evaluated, as tubes, which are anatomically patent under high pressure, may be functionally deficient.
