Similar to the stomach and colon, the duodenum also demonstrates a fine mucosal relief pattern on double-contrast radiographic examination. Two patterns may be identified--fine reticular and "small dot." In order to investigate the origin of these patterns, duodenal bulb specimens were obtained at autopsy, and macroscopic and microscopic features were correlated with radiographic patterns. Findings indicate that the surface patterns identified radiographically on cadaveric specimens and in live patient subjects are due to villi and the collections of barium within the intervening sulci. Knowledge of this normal pattern will prevent misdiagnoses, especially when inflammatory disease of the duodenum is being considered.
与胃和结肠相似，十二指肠在双重对比造影检查中也显示出精细的黏膜纹理模式。可识别出两种模式——精细网状和“小点状”。为了研究这些模式的起源，在尸检时获取了十二指肠球部标本，并将宏观和微观特征与放射学模式进行了关联。研究结果表明，在尸体标本和活体患者身上通过放射学识别出的表面模式是由于绒毛以及其间沟内的钡剂聚集所致。了解这种正常模式将有助于防止误诊，尤其是在考虑十二指肠炎症性疾病时。
