    Hysterosalpingo-radionuclide scintigraphy (HERS) uses a radioactive tracer to assess female reproductive system pathway patency. This noninvasive method accurately images and evaluates the migration of tracers from the vagina to the peritoneal cavity and ovaries.

    Area of Science:

    • Reproductive Medicine
    • Nuclear Medicine
    • Gynecologic Imaging

    Background:

    • Evaluating the patency of female reproductive pathways is crucial for diagnosing infertility and other gynecologic conditions.
    • Conventional methods like hysterosalpingography (HSG) and peritoneoscopy (PCP) have limitations in imaging tracer migration and functional assessment.
    • There is a need for a simple, noninvasive imaging technique to assess the entire pathway from the vagina to the peritoneal cavity.

    Purpose of the Study:

    • To introduce and evaluate hysterosalpingo-radionuclide scintigraphy (HERS) as a novel radionuclide procedure.
    • To assess the migration of a particulate radioactive tracer (Technetium-99m human albumin microspheres) through the female reproductive tract.
    • To functionally image and determine the patency of the pathways from the vagina to the peritoneal cavity and ovaries.

    Main Methods:

    • HERS was performed by depositing Technetium-99m human albumin microspheres in the posterior fornix of patients.
    • Two groups were studied: Group I (undergoing gynecologic surgery) and Group II (infertility patients).
    • Radioactivity levels were measured in removed organs (Group I), and HERS was compared with HSG and PCP (Group II).

    Main Results:

    • HERS accurately demonstrated the migration of 99mTc-HAM from the vagina, through the uterus and fallopian tubes, to the peritoneal cavity and ovaries.
    • Radioactivity measurements in surgical specimens confirmed tracer distribution.
    • Comparison with conventional methods validated HERS's ability to assess pathway patency.

    Conclusions:

    • HERS is a simple, noninvasive radionuclide procedure for functionally imaging the female reproductive system.
    • The method accurately assesses the patency of pathways from the vagina to the peritoneal cavity and ovaries.
    • HERS provides valuable diagnostic information for infertility and gynecologic evaluations.
