High frequency ultrasound can resolve the structure of the wall of the gastro-intestinal tract into three highly echogenic lines with poorly echogenic zones between them. Sequential removal of layers of the walls of fresh specimens of the gastro-intestinal tract showed the following correlation between the sonographic and histological findings: the innermost and outermost highly echogenic lines correspond to incident and exit echoes. The middle line corresponds with the sub-mucosa and the junctional zones of the mucosa/muscularis mucosa and sub-mucosa/muscularis propria. The intervening low echo lines correspond with the mucosa and muscularis propria.
高频超声能够将胃肠道壁的结构分辨为三条高回声线，其间为低回声区。对新鲜胃肠道标本各层进行逐层去除后发现，超声检查结果与组织学检查结果存在以下对应关系：最内层和最外层的高回声线分别对应入射回声和出射回声。中间线对应于黏膜下层以及黏膜/黏膜肌层交界处和黏膜下层/固有肌层交界处。其间的低回声线对应于黏膜层和固有肌层。
