Summary

This study looked at whether PET scans can better detect endometriosis lesions before surgery compared to standard MRI and ultrasound. Fifteen women with symptomatic endometriosis scheduled for surgery received a PET scan, and the results were compared with what surgeons actually found. The goal was to see if PET scans could help surgeons know exactly where the lesions are, potentially leading to more complete treatment.
