This 2009 study investigated the anatomic distribution of posterior deeply infiltrating endometriosis using MRI, with vaginal and rectal gel opacification to enhance visualization of pelvic structures. Using an adult female population, the authors assessed where posterior deep lesions were located relative to pelvic anatomy on the opacified MRI images. The key finding was a detailed mapping of lesion distribution patterns in the posterior compartment, characterized by consistent involvement of specific anatomic sites. A major limitation stated by the authors is that MRI interpretation depends on the imaging preparation and lesion detectability, which can influence observed distribution. This paper is centrally about endometriosis — it specifically analyzes the anatomic distribution of posterior deeply infiltrating endometriosis on MRI after vaginal and rectal gel opacification.

Abstract

OBJECTIVE: 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. CONCLUSION: We show the capability and potential of MRI in diagnosing and staging of posterior deeply infiltrating endometriosis after vaginal and rectal gel opacification.
