Endoscopic ultrasound imaging has potential for improving the diagnosis of gastrointestinal disease. However, the anatomic correlates of gastrointestinal ultrasound images have not been precisely defined. We have compared ultrasound images with the corresponding histologic sections of 81 specimens of resected and postmortem, normal and diseased gastrointestinal tissue. The five layers seen on ultrasound images of the normal gastrointestinal tract correspond to (1) superficial mucosa, (2) deep mucosa, (3) submucosa plus the acoustical interface between the submucosa and muscularis propria, (4) muscularis propria minus the acoustical interface between the submucosa and muscularis propria, and (5) serosa and subserosal fat. This interpretation takes into consideration the echoes produced by the tissue layers and the echoes produced by the interfaces between layers. Abnormal findings on ultrasound images of neoplastic and inflammatory diseases correspond to histologic tissue structure. When properly interpreted, ultrasound images of the gastrointestinal wall can provide potentially useful diagnostic information.
内镜超声成像在改善胃肠疾病诊断方面具有潜力。然而，胃肠超声图像的解剖学对应关系尚未得到精确界定。我们将超声图像与81份切除及尸检的正常和患病胃肠组织标本的相应组织学切片进行了比较。正常胃肠道超声图像上所见的五层分别对应于：（1）浅表黏膜；（2）深层黏膜；（3）黏膜下层加上黏膜下层与固有肌层之间的声学界面；（4）固有肌层减去黏膜下层与固有肌层之间的声学界面；（5）浆膜和浆膜下脂肪。这种解释考虑了各组织层产生的回声以及各层之间界面产生的回声。肿瘤性和炎症性疾病超声图像上的异常表现与组织学组织结构相对应。当得到正确解释时，胃肠壁的超声图像可提供潜在有用的诊断信息。
