Early radiological changes in ulcerative colitis include (a) finely granular mucosa due to hyperemia and edema, (b) mucosal stippling due to adherence of barium to superficial ulcers, and (c) coarsely granular mucosa due to ingrowth of granulation tissue. In granulomatous colitis, early changes include discrete, superficial ulcers, often against a background of normal mucosa, seen best en face. All of these changes can be demonstrated by the double-contrast technique. The radiological and endoscopic findings were in agreement in 95% of the examinations in the authors' series. The importance of the technical aspects of the examination is stressed.
（a）由于充血和水肿导致黏膜呈细颗粒状；（b）由于钡剂附着于浅表溃疡而出现黏膜斑点状；（c）由于肉芽组织长入导致黏膜呈粗颗粒状。在肉芽肿性结肠炎中，早期改变包括散在的浅表溃疡，通常在正常黏膜背景下出现，正面观显示最佳。所有这些改变都可以通过双对比技术显示。在作者的系列研究中，95%的检查中放射学和内镜检查结果一致。强调了检查技术方面的重要性。
