Technetium-99m hysterosalpingography in infertility: an accurate alternative to contrast hysterosalpingography.

Thirteen infertile women who had undergone tubal surgery within the previous year for the correction of tubal obstruction, were studied with both conventional and radionuclide hysterosalpingography. The studies were performed on the same day, were interpreted independently, and the results were then compared. Three cases were excluded from analysis because of the technical inadequacy of one of the studies. Assuming the findings of the conventional studies to represent "truth," the sensitivity, specificity and accuracy of the radionuclide studies were 100%, 60% and 80% respectively.
