Radiological synopsis of primary gastrointestinal lymphoma depends on the growth direction and dynamism of the tumor, i.e. grade of malignancy and stage of the pathological processes at diagnosis. Initial nodal-polypoid lesions, because of their mucosal/submucosal aggregation, in combination with more or less pathological small bowel relief, are successfully diagnosed by conventional barium studies. Progressive ulcerous and narrowing destruction of the gut wall, as a result of the advanced mural infiltration, increases the success rate of tomographic examination. Tomographic imaging, particularly computed tomography, is considered the primary method, alongside the selective small bowel double-contrast study for demonstration of diffuse tumor infiltration.
原发性胃肠道淋巴瘤的放射学概要取决于肿瘤的生长方向和动态变化，即诊断时的恶性程度和病理过程阶段。最初的结节状息肉样病变，由于其在黏膜/黏膜下层的聚集，结合或多或少的病理性小肠形态，通过传统钡剂检查可成功诊断。由于壁层浸润进展导致肠壁出现进行性溃疡和狭窄性破坏，提高了断层扫描检查的成功率。断层成像，尤其是计算机断层扫描，被认为是主要方法，同时选择性小肠双对比造影用于显示弥漫性肿瘤浸润。
