The authors investigated the role of CT in the study of intrinsic mural pathologic conditions originating from submucosal/muscular layers and of extrinsic conditions due to extraintestinal disease with secondary spread to the alimentary tract. According to the various diagnostic problems, either hypodense contrast agents (air, corn-oil emulsion, and water) or hyperdense contrast agents (iodine solutions, and barium suspensions) can be used to fill intestinal guts. Normal intestinal wall thickness does not exceed 5 mm. In case of intrinsic mural conditions, CT allows tumor extent to be evaluated, and, on the basis of densitometric values, makes the diagnosis of lipoma possible. As for intrinsic conditions (varices), CT yields specific findings. This is not the case with intestinal infarction, intramural hematoma, and phlogistic conditions, where CT generally shows aspecific parietal thickness. As for extrinsic mural conditions, CT demonstrates alimentary tract involvement due to phlogistic/neoplastic extraintestinal conditions, for it allows intestinal guts to be depicted, and the adjacent organs and structures. CT is a complementary method to conventional radiology and endoscopy which has given an excellent contribution to the study of mural pathologic conditions.
作者研究了CT在源于黏膜下层/肌层的肠壁内病变以及因肠外疾病继发蔓延至消化道的肠壁外病变研究中的作用。根据各种诊断问题，可使用低密度造影剂（空气、玉米油乳剂和水）或高密度造影剂（碘溶液和钡剂混悬液）来充盈肠道。正常肠壁厚度不超过5mm。对于肠壁内病变，CT可评估肿瘤范围，并根据密度测量值作出脂肪瘤的诊断。对于肠壁内病变（静脉曲张），CT可产生特异性表现。而对于肠梗死、壁内血肿和炎症性病变，情况并非如此，CT通常显示肠壁厚度非特异性增加。对于肠壁外病变，CT可显示由于炎症性/肿瘤性肠外病变导致的消化道受累情况，因为它能够描绘肠道以及相邻器官和结构。CT是传统放射学和内镜检查的补充方法，为肠壁病变的研究做出了卓越贡献。
