Magnetic resonance (MR) imaging at 0.35 T showed limited accuracy in detecting pelvic endometriosis, with a 63% overall accuracy. Laparoscopy remains the preferred method for diagnosis and staging.

Area of Science:

  • Radiology
  • Gynecology

Background:

  • Pelvic endometriosis is a common gynecological condition requiring accurate diagnosis.
  • Magnetic resonance (MR) imaging is a non-invasive modality explored for evaluating endometriosis.

Purpose of the Study:

  • To prospectively assess the diagnostic value of 0.35 T MR imaging in detecting, characterizing, and staging pelvic endometriosis.
  • To compare MR imaging findings with surgical outcomes.

Main Methods:

  • 30 women with suspected pelvic endometriosis underwent 0.35 T MR imaging.
  • MR findings were correlated with surgical findings from laparoscopy (13) or laparotomy (17).

Main Results:

  • MR imaging correctly identified endometriosis in 16 of 25 cases (64% sensitivity, 60% specificity, 63% accuracy).

  • Endometriomas were detected well (7/8), but adhesions (14/29) and implants (6/45) were poorly visualized.
  • MR imaging failed to accurately depict extraovarian adhesions and intraperitoneal implants, and did not correlate with disease severity.

    • Conclusions:

    • 0.35 T MR imaging has limitations in detecting and staging pelvic endometriosis, particularly adhesions and implants.
    • Laparoscopy remains the gold standard for the diagnosis, characterization, and staging of endometriosis.
