Despite the availability and wide use of modern imaging techniques, the diagnosis of Meckel's diverticulum is difficult. The signs and symptoms vary from none to those of an acute abdomen or gastrointestinal bleeding. Findings on physical examination may be inconsistent because of the variable location of the diverticulum, and bleeding may occur with no appreciable physical findings. Finally, small diverticula are often concealed by overlying small-bowel loops on routine small-bowel barium studies. The purposes of this article are to review the use of available techniques for the imaging diagnosis of Meckel's diverticulum, to discuss the relative advantages and indications for the various procedures, and to emphasize the role each plays in specific clinical circumstances. The embryology, anatomy, and clinical presentation of Meckel's diverticulum are also briefly discussed.
尽管现代成像技术已广泛应用，但梅克尔憩室的诊断仍很困难。其体征和症状差异很大，从无任何症状到急腹症或胃肠道出血的症状都有可能。由于憩室位置多变，体格检查结果可能不一致，而且可能在没有明显体格检查发现的情况下发生出血。最后，在常规小肠钡剂造影检查中，小的憩室常被覆盖其上的小肠袢遮挡。本文的目的是回顾用于梅克尔憩室成像诊断的现有技术的应用，讨论各种检查方法的相对优势和适应证，并强调每种方法在特定临床情况下所起的作用。同时，还简要讨论了梅克尔憩室的胚胎学、解剖学和临床表现。
