本文总结了常见胃肠道肿瘤的临床特点和影像学特点。钡剂检查可用于显示原发性恶性肿瘤，并且具有微创或无创性。肿瘤可表现为各种影像学表现，包括粘膜破坏、软肿块、溃疡、粘膜下浸润和钡剂检查管腔狭窄。良性肿瘤通常表现为边缘光滑的壁内肿块。恶性肿瘤在钡剂检查中通常表现为不规则的浸润性病变。肿瘤向邻近GI节段的延伸在钡剂图像上可能不清楚。横截面图像，如计算机断层扫描和磁共振成像可以提供更准确的细节，邻近器官的侵犯，网膜或腹膜蔓延。
This article summarizes the clinical characteristics and imaging features of common gastrointestinal (GI) neoplasms in terms of conventional radiological imaging methods. Barium studies are readily available for displaying primary malignancies and are minimally or not at all invasive. A neoplasm may be manifested as various imaging findings, including mucosal disruption, soft mass, ulcer, submucosal invasion and lumen stenosis on barium studies. Benign tumors typically appear as smoothly marginated intramural masses. Malignant neoplasms most often appear as irregular infiltrative lesions on barium examination. Tumor extension to adjacent GI segments may be indistinct on barium images. Cross-sectional images such as computed tomography and magnetic resonance imaging may provide more accurate details of the adjacent organ invasion, omental or peritoneal spread.
