title: Deep infiltrating endometriosis: Should rectal and vaginal opacification be systematically used in MR imaging?
abstract: OBJECTIVE
  To evaluate the interest of rectal and vaginal filling in vaginal and recto-sigmoid endometriosis with MR imaging. To compare the results between a senior and a junior radiologist review.
  
  
  METHODS
  Sixty-seven patients with clinically suspected deep infiltrating endometriosis were included in our MRI protocol consisting of repeated T2-weigthed sequences (axial and sagittal) before and after rectal and vaginal marking with ultrasonography gel. Vaginal and recto-sigmoid endometriosis lesions were analyzed before and after opacification. The inter-reader agreement between senior and junior scores was studied.
  
  
  RESULTS
  Concerning vaginal and muscularis and beyond colonic involvement, no significant difference (P=0.32) was observed and the inter-reader agreement was excellent (K=0.96 and 0.97 respectively). Concerning serosa colonic lesions, a significant difference was observed (P=0.01) and the inter-reader agreement was poor (K=0).
  
  
  CONCLUSIONS
  Rectal and vaginal filling in endometriosis staging with MRI is not necessary no matter the reader experiment.
