[摘要] 目的 对比分析原发性胃淋巴瘤CT和MRI影像学表现。 方法 方便选择2014年10月—2017年10月期间该院收治的38例原发性胃淋巴瘤患者作为研究对象。该组患者术前均先行CT扫描，再行MRI扫描，对比分析CT和MRI影像学表现。结果CT和MRI对病变位置、范围、与邻近胃壁的关系、周围组织器官侵犯及淋巴结转移情况诊断效果均较好。在累及黏膜、黏膜线中断和淋巴结转移检出率方面，CT和MRI诊断比较，差异无统计学意义（χ2=0.000，0.337，P=1.000，0.337）；MRI对累及浆膜层检出率高于CT，差异有统计学意义（χ2=5.204，P=0.021）。结论 原发性胃淋巴瘤CT和MRI均具有较高的诊断价值，可根据影像学表现为临床诊断提供确切资料，必要时可联合检测，以提高临床诊断准确性。

[Abstract] Objective To compare and analyze the CT and MR image manifestations of primary gastric lymphoma. Methods 38 cases of patients with primary gastric lymphoma admitted and treated in our hospital from October 2014 to October 2017 were convenient selected as the research objects and underwent the CT scanning before surgery and MRI scanning， and the CT and MRI imaging manifestations were compared and analyzed. Results The effect of CT and MRI in diagnosis of lesion site， range， correlation with the adjacent gastric wall， organ invasion of peripheral tissues and lymphatic metastasis was better， and the differences in the test rates of involved mucosa， discontinuity of mucous line and lymphatic metastasis between the CT and MRI were not statistically significant（χ2=0.000，0.337，P=1.000，0.337）， and the test rate of MRI in the involved serosa layer was higher than that of CT， and the difference was statistically significant（χ2=5.204，P=0.021）. Conclusion The CT and MRI in the primary gastric lymphoma have a higher diagnosis value， and we can provide definite data for the clinical diagnosis according to the imaging manifestations， if necessary， the combined test can be conducted to improve the accuracy of clinical diagnosis.

原發性胃淋巴瘤属于结外淋巴瘤，是一种发病率相对较低的胃原发恶性肿瘤，以非霍奇金淋巴瘤为主，组织病理学分型较多上，弥漫大B细胞型等相对较多，T 细胞型淋巴瘤等相对较少[1]。原发性胃淋巴瘤预后多不良，且与胃间质瘤等胃部肿瘤相似性较高，临床误诊率高，需进一步提高其诊断水平[2]。CT和MRI是腹部恶性肿瘤的常用诊断手段，为进一步探明两者对于原发性胃淋巴瘤诊断价值，该次研究方便选择2014年10月—2017年10月期间该院收治的38例原发性胃淋巴瘤患者作为研究对象，对比分析了CT和MRI影像学表现，现报道如下。
