Endoscopy and radiological imaging are complementary. However the gastro-intestinal tract is routinely being imaged in CT and ultrasound, often performed for other indications. When an abnormality is discovered, several questions have to be addressed. Is the lesion due to a bowel abnormality? When bowel wall thickening is present, is it due to poor opacification or is it due to inflammation or tumor? Circumferential symmetrical thickening is more in favor of an inflammatory lesion, while focal asymmetrical thickening is more in favor of a neoplastic lesion. Inflammatory and lymphomatous lesion can have similar appearances. Guidelines to aid in diagnostic interpretation of gastrointestinal lesions are discussed, including features of appendicitis and obstruction.
内镜检查与放射影像学检查相辅相成。然而，胃肠道通常会在CT和超声检查中成像，这些检查往往是因其他指征而进行的。当发现异常时，必须解决几个问题。该病变是否由肠道异常引起？当出现肠壁增厚时，是由于造影剂充盈不佳，还是由于炎症或肿瘤？环形对称增厚更倾向于炎症性病变，而局灶性不对称增厚更倾向于肿瘤性病变。炎症性病变和淋巴瘤性病变可能有相似的表现。本文讨论了有助于胃肠道病变诊断解读的指南，包括阑尾炎和肠梗阻的特征。
