Abstract:
Fecal incontinence is a frequent condition. The workup of patients with fecal incontinence comprises clinical history, physical examination, anofunctional tests and imaging. In many institutions, imaging in these patients concerns endosonography. Magnetic resonance imaging (MRI) is a valuable alternative to endosonography. For detection of external sphincter defects the techniques have comparable results. However, visualization of the external sphincter at MRI is superior to endosonography, facilitating identification of external sphincter atrophy. External sphincter atrophy at MRI is related to poor outcome of anterior anal repair and therefore MRI should be considered in potential candidates for anterior anal repair. External coil MRI is a widely available alternative to endoanal MRI and can be used as an alternative in experienced hands.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
