Abstract
The pelvic floor is a complex 3D support structure for the pelvic organs. Weakness of one of the structures may be compensated for by the others but will predispose to eventual pelvic floor disorders.
Pelvic floor dysfunction is a relatively common condition occurring primarily in postmenopausal parous women with symptoms that can be functionally debilitating and embarrassing. These including urinary and fecal incontinence, difficulty voiding and defecating, pain, pressure, and pelvic organ prolapse.
Pelvic floor relaxation is usually a generalized condition involving, to certain extent, all compartments of the pelvic floor. The diagnosis of all compartments of pelvic prolapse is essential in surgical failure, recurrent prolapse and reoperations.
Dynamic and static MR imaging of the pelvic floor is an excellent modality for assessing anatomical and functional disorders of the pelvic floor in cases of pelvic organ prolapse, outlet obstruction, and incontinence. Findings reported at dynamic and static MR imaging of the pelvic floor are valuable for selecting candidates for surgical treatment and for indicating the most appropriate surgical approach, so combined analysis of both kinds of MR images can provide the clinician with complete mapping of the site and type of defects. Such information may help the clinician decide on physiotherapy for a patient with global muscle weakness and normal fascia but on surgical repair for a patient with a focal break in the fascia and/or a muscle tear.
MR defecography allows accurate assessment of anorectal morphology and function in relation to surrounding structures and it permits analysis of anorectal angle, the opening of the anal canal, and the descent of the pelvic floor during defecation.
Dynamic MRI defecography is a useful technique for the detection and characterization of pelvic floor abnormalities. Fast MRI sequences provide the possibility to investigate anorectal morphology and function in a dynamic fashion, showing all pelvic floor compartments and surrounding tissues with excellent contrast and without ionizing radiation exposure.
On conclusion in women with pelvic floor dysfunction, pelvic MRI, with its superior soft tissue contrast resolution, allows direct visualization of the pelvic organs and their supportive structures in a single noninvasive examination. Combined analysis of static and dynamic MR images allowed identification of certain structural abnormalities with specific dysfunction. MR defecography contributes to effective patient care by accurately evaluating dynamic anatomy of a patient presenting with obstructed defecation and the sequelae of pelvic floor weakness.
