Magnetic resonance imaging (MRI) shows comparable efficacy to hysterosalpingography (HSG) for detecting fallopian tube patency. This non-ionizing radiation imaging technique offers potential advantages for evaluating female reproductive health.

Area of Science:

  • Radiology
  • Reproductive Medicine
  • Medical Imaging

Background:

  • Hysterosalpingography (HSG) is the conventional method for assessing fallopian tube patency.
  • HSG involves ionizing radiation and potential contrast toxicity.

Purpose of the Study:

  • To evaluate the efficacy of Magnetic Resonance (MR) imaging compared to conventional HSG for detecting fallopian tube patency.
  • To assess the diagnostic accuracy of MR imaging in identifying tubal patency and obstruction.

Main Methods:

  • Rabbit uterine horns (n=18) underwent transvaginal catheterization.
  • MR imaging and conventional HSG were performed using contrast agents.
  • Images were analyzed by two blinded readers to determine tubal patency based on peritoneal spill.

Main Results:

  • MR imaging and conventional HSG showed no statistically significant difference in diagnosing fallopian tube patency.
  • Sensitivity and specificity for MR imaging were 95.5% and 70%, respectively.
  • Discrepancies were attributed to subtle spill, artifact, or bowel loop interference.

Conclusions:

  • MR imaging is a viable alternative to conventional HSG for evaluating fallopian tube patency.
  • MR imaging offers advantages such as no ionizing radiation and better visualization of pelvic structures.
  • Further studies, including primate models, are recommended to validate MR imaging for human anatomy.
