Drug: F-18 FES
F-18 FES PET/MRI for detection of endometriosis.

Primary Outcome Measures :
  1. Detection of Endometriosis [ Time Frame: 24 months ]
    Comparisons will be made descriptively between conventional MRI imaging, FES PET/MRI imaging and surgical/pathologic findings. Outcome data include number of detected lesions, differences in the accuracy for detection of active disease versus inactive fibrosis, and confidence score.
