title: Serial scintigraphic imaging for visualization of passive transport processes in the human fallopian tube.
abstract: Spontaneous migration of a radionuclide tracer from the vagina to the peritoneum may be visualized by scintigraphic imaging (hysterosalpingoscintigraphy, HSS). A prospective study was designed to evaluate diagnostic criteria for normal tubal passage of a control group (n = 7) and to establish the predictive value of the HSS technique in defining functional deficiency in anatomically patent tubes. In 56 patients with tubal and unexplained infertility, a comparison between the results of the tracer migration study and of contrast hysterosalpingography and laparoscopy was made. The overall correlation was 65%. Clearly discrepant results (i.e. an abnormal migration pattern in anatomically patent tubes) were recorded in 18% and were positively, yet not significantly associated with tubal adhesive disease and with a history of tubal microsurgery. Interpretation of scans was equivocal in another 18% of patients due to undetectable ascension of the tracer to the uterus. It is suggested that the radionuclide is moved forward by the same passive transport processes which are concerned with support of the migration of spermatozoa to the ovum, and that failure of tubal migration of the tracer may render patients eligible for in-vitro fertilization/embryo transfer treatment.
