In patients with inflammatory bowel disease (IBD), radiologic examinations are important for diagnosis and treatment. With conventional X-ray examinations, mucosal abnormalities, ulcers and fistulas can be visualised, but no information on the extramural extension of the disease can be obtained. Newer radiologic modalities (ultrasound, CT and MRI) offer new diagnostic possibilities. With ultrasound IBD can be diagnosed with good confidence and it can differentiate between Crohn's disease and ulcerative colitis. CT and MRI are indicated not so much to diagnose the disease but rather to determine the severity and spread of disease activity (transmural and extramural inflammation) and to detect complications such as fistulas and abscesses.
在炎症性肠病（IBD）患者中，放射学检查对诊断和治疗很重要。通过传统的X线检查，可以看到黏膜异常、溃疡和瘘管，但无法获得有关疾病壁外扩展的信息。更新的放射学检查方法（超声、CT和MRI）提供了新的诊断可能性。通过超声可以很有把握地诊断IBD，并且可以区分克罗恩病和溃疡性结肠炎。CT和MRI的主要作用并非诊断疾病，而是确定疾病活动的严重程度和范围（透壁和壁外炎症）以及检测诸如瘘管和脓肿等并发症。
