Different<unk>  modalities may be helpful in the diagnosis of<unk>  underlying diseases. Four types of<unk>  which are used for diagnosing<unk>  are conventional pelvic<unk> , dynamic<unk>  (MR defecography), endoanal<unk> , and fluoroscopic<unk> .

Findings on MR defecography suggestive of<unk>  include various types of rectal prolapse (mucosal or full-thickness), disorders of pelvic floor muscles movements, very acute anorectal angle, and Increased perineal descent degree during rectal evacuation. The major findings on endoanal<unk>  are thinning of sphincter muscles, disruption of sphincter muscles, and changes in the anorectal angle.<unk>  fluoroscopy is a real time modality that evaluates the pelvic floor and viscera during defecation, valsalva maneuver, and evacuation process.
