Gastrointestinal lymphomas can occur in nodular, polypoid, cavitary, ulcerative or diffuse infiltrating (submucosal) forms. Barium studies and computed tomography (CT) are the most popular imaging techniques used to diagnose these lymphomas. Barium studies are superior to CT in evaluating mild mucosal and submucosal changes. However, CT is the technique of choice because it provides a complete evaluation of the extent of disease dissemination, recent disease development, therapeutic response, and related complications.
胃肠道淋巴瘤可表现为结节状、息肉样、囊状、溃疡性或弥漫浸润性（黏膜下）。钡剂造影和计算机断层扫描（CT）是诊断这些淋巴瘤最常用的影像学技术。钡剂造影在评估轻微黏膜和黏膜下改变方面优于 CT。然而，CT 是首选技术，因为它可以全面评估疾病扩散程度、近期病情发展、治疗反应和相关并发症。
