用8.5 MHz超声（US）检查6例正常和16例肿瘤性结直肠标本。一个铰接系统促进了精确的空间相关性之间的US和组织切片。图像盲解，然后与组织学结果进行比较。所有6例正常标本均显示5个不同的回声层，所有观察者均能将其与肿瘤标本区分开来。中央回声层，对应于粘膜下层，在确定肿瘤起源的深度和粘膜下层浸润的存在方面是有用的。超声对粘膜下层浸润的诊断准确率为92.5%，对肌层浸润的诊断准确率为77%。对于粘膜肿瘤通过外肌层侵犯并延伸到浆膜下组织，近90%的US解释是正确的。高频超声可用于确定粘膜肿瘤相对于粘膜下层的浸润深度，并区分粘膜与壁外肿块。
Six normal and 16 neoplastic colorectal specimens were examined with 8.5-MHz ultrasound (US). An articulated system facilitated precise spatial correlation between US and histologic sections. Images were blindly interpreted and then compared with histologic results. All six normal specimen showed five distinct echo layers and were distinguished from neoplastic specimens by all the observers. The central echogenic layer, corresponding to the submucosa, is useful in determining the depth of origin of a neoplasm and the presence of submucosal invasion. US had an accuracy of 92.5% in demonstrating invasion of the submucosa and 77% for invasion of the muscularis externa. For mucosal neoplasms with invasion through the muscularis externa and extension into the subserosal tissues, nearly 90% of US interpretations were correct. High-frequency US may be useful in determining the depth of invasion of mucosal tumors with respect to the submucosa and in differentiating mucosal from extramural masses.
