THE IMPACT OF DEFECOGRAPHY MAGNETIC RESONANCE IMAGING IN CLINICAL PRACTICE

Introduction Defecographic magnetic resonance imaging is an advanced technique that plays a crucial role in diagnosing pelvic floor disorders through a dynamic study that analyzes the morphology and functionality during defecation. It is particularly useful in the differential diagnosis of pelvic organ prolapse, evacuation disorders, and continence issues, enabling more effective clinical and surgical approaches.

Objective To explain the effectiveness of Defecographic Magnetic Resonance Imaging in identifying pelvic floor disorders and exemplify its application in clinical practice, aiming to improve the diagnosis and treatment of these conditions.

Method A pictorial essay and analysis of clinical cases where dynamic defecography by MRI was used, comparing diagnostic results with other imaging techniques such as fluoroscopy and ultrasonography.

Results Compared to clinical examination and other imaging methods, defecographic MRI was able to diagnose a higher proportion of patients with multi-compartmental perineal disorders. Additionally, it was more accurate than clinical examination alone in identifying pelvic organ prolapse and significantly better in identifying cystocele, rectal prolapse, and enterocele. In patients with symptoms of pelvic floor disorders, defecographic MRI provides additional information beyond clinical examination. Therefore, it is indicated for symptomatic patients with negative clinical findings or suspected multi-compartmental pelvic floor involvement.

Conclusion The ability to provide detailed and dynamic visualization of pelvic structures enhances diagnostic accuracy and guides more effective therapeutic interventions. Wider adoption of defecographic MRI, combined with a multidisciplinary approach, is crucial for achieving better clinical outcomes.
