Summary
Magnetic resonance imaging (MRI) defaecography shows pelvic floor disorders in faecal incontinence (FI). However, MRI agreement with clinical examination is poor, except for anterior rectocoele, indicating limited diagnostic value for FI assessment.
Area of Science:
- Pelvic floor disorders
- Gastroenterology
- Diagnostic imaging
Background:
- Faecal incontinence (FI) necessitates thorough etiological assessment for effective treatment.
- Pelvic floor disorders are a common cause of FI, impacting quality of life.
Purpose of the Study:
- To evaluate MRI defaecography in patients with FI.
- To compare MRI defaecography with clinical examination and rectoscopy for pelvic floor assessment in FI.
Main Methods:
- Retrospective study of 74 female patients with FI undergoing MRI defaecography.
- Comparison of MRI findings with clinical examination, anuscopy, and rectoscopy results.
Main Results:
- MRI defaecography identified internal intussusception (25.7%) and pelvic floor descent (32.4%).
- Average agreement was found for anterior rectocoele (κ=0.40).
- Poor agreement was observed for intra-rectal (κ=0.06) and intra-anal intussusception (κ=0.11).
Conclusions:
- MRI defaecography shows poor correlation with clinical examination for most pelvic floor disorders in FI, except anterior rectocoele.
- MRI can detect various static and dynamic pelvic disorders, including enterocoele.
- Findings may influence surgical approaches for intussusception and anterior rectocoele.

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
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.
In gastric emptying studies, a meal's liquid and...

01:25Assessment of the Rectum and Anus
2.0K
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
