历史上，钡和同位素研究被用于炎症性肠道疾病（IBD）的成像，但存在辐射暴露的风险。钡的使用正在减少，导致具有必要专业知识的放射科医生减少。同位素研究缺乏解剖学定义，但18F -氟脱氧葡萄糖（FDG）正电子发射断层扫描（PET）显示出与内窥镜相比准确评估疾病的前景。计算机断层扫描（CT）在评估克罗恩病（CD）的并发症中特别有用，但辐射暴露量很高。CT小肠造影（CTE）改善了小肠粘膜疾病的可视化，并可评估疾病活动性。超声越来越多地用于潜在IBD患者的初步评估。尽管这种专门知识广泛提供，而且在经济上也很有吸引力，但所需的专门知识并不普遍。最后，磁共振成像（MRI）被证明是评估疾病范围和分布的最准确工具。骨盆MRI在评价阴茎肛瘘方面已取代其他技术。(C)2014由Elsevier Ltd.出版
Historically Barium and isotope studies been used for imaging of inflammatory bowel disease (IBD) but carry risk of radiation exposure. Use of Barium is declining resulting in fewer radiologists that have the necessary expertise. Isotopes studies lack anatomical definition but 18F - fludeoxyglucose (FDG) positron emission tomography (PET) shows promise in accurate assessment of disease compared to endoscopy. Computerised tomography (CT) is particularly useful in assessment of complications of Crohn's disease (CD) but radiation exposure is high. CT enterography (CTE) has improved visualisation of small bowel mucosal disease and allows assessment of disease activity. Ultrasound is increasingly used for preliminary assessment of patients with potential IBD. Although widely available and economically attractive, the expertise required is not widespread. Finally magnetic resonance imaging (MRI) is proving to be the most accurate tool for assessment of disease extent and distribution. MRI of the pelvis has superseded other techniques in assessment of pen-anal fistulation. (C) 2014 Published by Elsevier Ltd.
