To evaluate the frequency of pathological findings determined on magnetic resonance (MR) enterography (MRE) in patients with Crohn's Disease.
A retrospective analysis of the MRE images was made in 34 female and 41 male patients (mean age 41 years) with Crohn's disease. The prevalence of bowel wall (mural thickening, mural edema, mural fat deposits, mucosal enhancement, ulceration, cobblestone appearance, pseudopolyps) and mesenteric fatty tissue alterations (fatty tissue proliferation, mesenteric hypervascularity, enlarged lymph nodes, peri-enteric inflammation, reactive fluid), complications due to penetrating (fistula, sinus tract, abscess) and stenosing processes (fibrotic and inflammatory stenosis, obstruction, dilatation), and involvement of the colon were determined.
The most frequently observed changes in the bowel wall and mesenteric fatty tissue were mural thickening (98.7%) and enlargement of mesenteric lymph nodes (76%), respectively. Stenosis was the most common complication (76%). The most frequently seen pathology of the colon was ileocecal valve thickening and enhancement (74.7%).
MR enterography is a useful imaging modality for the evaluation of changes in both the mesenteric fatty tissue and the bowel wall. As there is no use of ionizing radiation, MR enterography should be the preferred imaging modality during follow-up of patients with Crohn's disease.
评估磁共振肠造影（MRE）中克罗恩病患者的病理发现频率。
对 34 名女性和 41 名男性克罗恩病患者（平均年龄 41 岁）的 MRE 图像进行回顾性分析。评估肠壁（壁增厚、壁水肿、壁脂肪沉积、黏膜增强、溃疡、鹅卵石样外观、假息肉）和肠系膜脂肪组织改变（脂肪组织增生、肠系膜高血管化、淋巴结肿大、肠周炎症、反应性积液）、穿透性（瘘管、窦道、脓肿）和狭窄性（纤维化和炎症性狭窄、梗阻、扩张）并发症以及结肠受累的发生率。
肠壁和肠系膜脂肪组织最常观察到的改变分别为壁增厚（98.7%）和肠系膜淋巴结肿大（76%）。狭窄是最常见的并发症（76%）。结肠最常见的病理学表现为回盲瓣增厚和增强（74.7%）。
磁共振肠造影术是一种评估肠系膜脂肪组织和肠壁变化的有用成像方式。由于不使用电离辐射，磁共振肠造影术应成为克罗恩病患者随访的首选成像方式。
