Fecal incontinence is often multifactoral. Clinical examination may not detect the cause in at least 25% of patients. The choice of an optimal therapy is determined on the basis of a proper assessment, especially accurate images of the anal sphincter complex. Over the last decade, technical advances in anal imaging have increased the significant impact of imaging on the management of patients with fecal incontinence. As described in the preceding chapters, a number of imaging methods, such as defecography, endoanal ultrasonography, dynamic and three-dimensional (3D)-endoluminal ultrasonography, transperineal and transvaginal ultrasonography, and dynamic magnetic resonance imaging (MRI), are employed for the diagnosis of incontinence.
