Detection of Tc-99m labelled albumin particles in the Fallopian tubes after intraperitoneal deposition.

Objective: To study the Fallopian tube uptake of intra-abdominal albumin particles.

Study Design: Six healthy women volunteered for ultrasound guided deposition of Tc-99m labelled albumin particles into the pouch of Douglas, before undergoing sterilisation by salpingectomy.

Results: On gamma camera images radioactivity spread evenly over the parietal peritoneum.

Radioactivity in cervical mucus after intraperitoneal deposition of Tc-99m labelled albumin particles before and after sterilisation.

Objective: To study the transport of radiolabelled albumin particles from the pouch of Douglas to cervical mucus.

Study Design: A prospective randomised study, including 10 healthy women, undergoing laparoscopic sterilization. A solution of human serum albumin particles, labelled with Technetium 99(m) (Tc-99(m)) was injected into the pouch of Douglas, either before or after sterilisation.

Radionuclide hysterosalpingography is not predictive in the diagnosis of infertility.

Objective: To investigate whether radionuclide hysterosalpingography (radionuclide HSG), which has been suggested as a more functional approach to the diagnosis of tubal infertility than conventional patency tests, is predictive in the diagnosis of infertility.

Design: A retrospective analysis of data from an inquiry form containing questions about pregnancy outcome after radionuclide HSG.

Setting: University hospital-based, tertiary care infertility clinic.

Radionuclide hysterosalpingography does not distinguish between fertile women, before tubal sterilization, and infertile women.

The female genital tract is capable of active transport that can be demonstrated by serial scintigraphic imaging over time (radionuclide hysterosalpingography; RN-HSG). RN-HSG has been suggested to offer a more functional approach to tubal infertility diagnosis than conventional patency tests. However, before RN-HSG can be recommended as a routine method, its reliability in showing active transport in fertile women must be demonstrated.

Developmental steps for radionuclide hysterosalpingography.

The active oviductal transportation capacity was studied in 73 infertile women by the use of a new deposition technique of radioactive particles into the internal cervical os. The main reason for this study was that a previous observation had shown that such a transportation capacity was lacking in 41% of the infertile patients with a normal hysterosalpingogram. The examination was performed in the immediate preovulatory phase, i.
