Magnetic resonance (MR) hysterosalpingography is feasible for imaging fallopian tubes. This phantom study refined a rapid acquisition with relaxation enhancement (RARE) sequence to visualize normal and diseased tubes.

Area of Science:

  • Radiology
  • Medical Imaging
  • Gynecologic Imaging

Background:

  • Magnetic resonance (MR) imaging offers advanced visualization capabilities for pelvic anatomy.
  • Developing non-invasive imaging techniques for evaluating fallopian tube patency is crucial in gynecologic diagnostics.

Purpose of the Study:

  • To develop and optimize a magnetic resonance (MR) hysterosalpingography pulse sequence and protocol.
  • To assess the feasibility of MR hysterosalpingography using a simulated pelvic phantom model.

Main Methods:

  • A phantom simulating the uterus, fallopian tubes, and pelvic cavity was created.
  • T2-weighted acquisition strategies, including rapid acquisition with relaxation enhancement (RARE), were refined.
  • Contrast agent properties and imaging parameters were varied, and digital image subtraction was employed.

Main Results:

  • The optimized RARE sequence with an 8-second interacquisition interval and 5 mL of sterile water yielded high-quality images.
  • The technique reliably depicted simulated normal fallopian tubes, free spill, unilateral, and bilateral hydrosalpinx.

Conclusions:

  • This phantom study demonstrates the feasibility of MR hysterosalpingography.
  • The developed technique shows promise for visualizing both normal and diseased fallopian tubes.
