There are various methods that could be used for small bowel imaging. Although conventional enteroclysis has a high sensitivity in the diagnosis of most of the small bowel diseases, it cannot provide any direct information about the mural-extramural diseases and the other abdominal structures. Besides, enteroclysis-based techniques have risk of additional radiation exposure, and they are poorly tolerated because placement of nasojejunal tube is required. New enterographic methods have been developed, and the number of enterographic techniques increased significantly in the recent years to overcome those limitations. The other modalities including ultrasound, small bowel follow-through, or capsule-endoscopy are often used as complementary methods in evaluation of the small bowel diseases. In this review, technique and clinic details, advantages, and disadvantages of the radiologic techniques that are used in the diagnosis of small bowel diseases, and the imaging findings of common pathologic conditions were discussed in the light of current literature.
有多种方法可用于小肠成像。尽管传统小肠灌肠造影对大多数小肠疾病的诊断具有较高的敏感性，但它无法提供有关肠壁外疾病和其他腹部结构的任何直接信息。此外，基于小肠灌肠造影的技术存在额外辐射暴露的风险，并且由于需要放置鼻空肠管，患者耐受性较差。近年来已开发出新的小肠造影方法，小肠造影技术的数量显著增加，以克服这些局限性。包括超声、小肠钡剂造影或胶囊内镜检查在内的其他检查方法常被用作评估小肠疾病的辅助方法。在本综述中，根据当前文献讨论了用于诊断小肠疾病的放射学技术的技术和临床细节、优缺点以及常见病理状况的影像学表现。
