Anatomic distribution of posterior deeply infiltrating endometriosis on MRI after vaginal and rectal gel opacification.

Abstract

The challenges of imaging posterior deeply infiltrating endometriosis with MRI are to image a small anatomic area encompassing several thin fibromuscular anatomic structures such as uterosacral ligaments, and the vaginal and rectal walls; and to image endometriotic lesions, which are fibromuscular structures and have an MRI signal intensity very close to those of surrounding fibromuscular anatomic structures. We show the capability and potential of MRI in diagnosing and staging of posterior deeply infiltrating endometriosis after vaginal and rectal gel opacification.
