Gadolinium-enhanced magnetic resonance (MR) imaging accurately detects and characterizes complex adnexal masses. This technique shows high diagnostic accuracy for malignancy and excellent agreement between observers.

Area of Science:

  • Radiology
  • Gynecologic Oncology
  • Medical Imaging

Background:

  • Complex adnexal masses require accurate diagnostic tools.
  • Distinguishing benign from malignant masses is critical for patient management.

Purpose of the Study:

  • To assess magnetic resonance (MR) imaging accuracy for complex adnexal masses.
  • To identify MR imaging features predictive of malignancy.
  • To evaluate the role of gadolinium contrast and observer variability.

Main Methods:

  • Preoperative pelvic MR imaging in 128 patients with 187 adnexal masses (96 malignant).
  • Independent review by two radiologists, with one re-evaluating after 6 months.
  • Multivariate logistic regression and receiver operating characteristic analysis were used.

Main Results:

  • Gadolinium-enhanced MR imaging detected 94% of masses with 93% accuracy for malignancy.
  • Necrosis in solid lesions and vegetations in cystic lesions strongly predicted malignancy.
  • Excellent inter- and intraobserver agreement (K values 0.79-0.86) was achieved.

Conclusions:

  • Gadolinium-enhanced MR imaging is highly accurate for adnexal mass detection and characterization.
  • The technique demonstrates excellent reliability among radiologists.
  • MR imaging findings, particularly necrosis and vegetations, are key predictors of malignancy.
