Summary
Magnetic resonance (MR) imaging enhances pelvic mass characterization in pregnant patients when sonograms are inconclusive. This advanced imaging technique improves diagnostic accuracy and can help avoid unnecessary surgeries.
Area of Science:
- Radiology
- Obstetrics & Gynecology
- Medical Imaging
Background:
- Pelvic masses in pregnant patients present diagnostic challenges.
- Sonography is the primary imaging modality, but characterization can be limited.
Purpose of the Study:
- To evaluate the value of magnetic resonance (MR) imaging in characterizing pelvic masses during pregnancy when sonography is suggestive but not definitive.
Main Methods:
- Retrospective review of 17 pregnant patients with pelvic masses evaluated by sonography and MR imaging.
- Analysis of lesion characteristics, origin, and impact on surgical planning.
Main Results:
- MR imaging improved lesion characterization in 47% of cases, correctly identifying masses like teratomas, fibroids, and endometriomas.
- MR imaging accurately determined the origin of pelvic masses in 100% of cases, compared to 71% for sonography.
- MR imaging findings led to the cancellation of surgery in three cases.
Conclusions:
- MR imaging is a valuable adjunct to sonography for preoperative evaluation of pelvic masses in pregnant patients.
- It enhances diagnostic accuracy and can optimize surgical decision-making, potentially preventing unnecessary procedures.
