Perianal fistulas represent one of the most critical complications of Crohn's disease (CD). Management and treatment need a multidisciplinary approach with an accurate description of imaging findings.
This study aspires to assess the significative role of Magnetic Resonance Imaging (MRI) in the study of perianal fistulas, secondary extensions, and abscess in patients with CD. Therefore it is essential to standardize an appropriate protocol of sequences that allow the correct evaluation of disease activity and complications.
We selected and reviewed ten recent studies among the most recent ones present in literature exclusively about pelvic MRI imaging and features in CD. We excluded studies that weren't in the English language.
MRI has a crucial role in the evaluation and detection of CD perianal fistulas because, thanks to its panoramic and multiplanar view, it gives excellent anatomic detail of the anal sphincters. Today MRI is the gold standard imaging technique for the evaluation of perianal fistulas, mainly because this technique shows higher concordance with surgical findings than does any other imaging evaluation. Surgical treatment is often required in the management of perianal fistula in patients with CD, which often have complex perineal findings.
本研究旨在评估磁共振成像（MRI）在评估 CD 患者肛周瘘管、继发延伸和脓肿中的重要作用。因此，标准化适当的序列方案以正确评估疾病活动度和并发症至关重要。
我们选择并回顾了文献中最近的十项关于盆腔 MRI 成像和 CD 特征的研究。我们排除了非英语的研究。
MRI 在评估和检测 CD 肛周瘘管中具有重要作用，因为它具有全景和多平面视图，可以极好地显示肛门括约肌的解剖细节。如今，MRI 是评估肛周瘘管的金标准成像技术，主要是因为与任何其他影像学评估相比，该技术与手术结果的一致性更高。在 CD 患者的肛周瘘管管理中，通常需要手术治疗，因为他们的会阴常存在复杂的表现。
