Ultrasonographically, the normal gastric wall is delineated in 5 layers, 2 hypoechoic layers and 3 hyperechoic layers. To elucidate the sources of the reflected ultrasonic picture above, we infused India ink into the ultrasonographic wall of the resected human stomach. After the ultrasonographic examination, each stomach was examined histologically, and findings were compared with those of ultrasonography. The results were as follows: Ultrasonographically, an irregular hypoechoic nodule was seen in the 3rd layer, i.e., the middle hyperechoic layer, in cases in which India ink was seen in the submucosal layer histologically. Namely, the ultrasonographic 3rd layer was considered to be consistent with the submucosal layer.
在超声检查中，正常胃壁可分为5层，包括2层低回声层和3层高回声层。为了阐明上述超声图像反射的来源，我们将印度墨汁注入切除的人体胃的超声壁中。超声检查后，对每个胃进行组织学检查，并将结果与超声检查结果进行比较。结果如下：在组织学检查中发现黏膜下层有印度墨汁的病例中，超声检查可见第三层（即中间高回声层）出现不规则低回声结节。也就是说，超声检查的第三层被认为与黏膜下层一致。
