摘　　要：目的分析MR小肠造影(MRE)对肠道T细胞淋巴瘤(ITCL)与肠道B细胞淋巴瘤(IBCL)的鉴别效能。方法回顾性分析2020年2月至2022年9月本院收治的结外非霍奇金淋巴瘤(NHL)患者98例,根据病理活检结果分别为ITCL组(n=32)与IBCL组(n=66)。收集患者的MRE检查结果,比较两组肠壁形态、病变部位、其他脏器受累情况、病灶强化方式、病变数量、并发症,分析ITCL、IBCL的MRE征象差异,并分析MRE对ITCL与IBCL的鉴别效能。结果98例NHL患者中,共有30例经MRE诊断为ITCL,共有68例经MRE诊断为IBCL。以病理活检结果为“金标准”,MRE鉴别ITCL与IBCL的灵敏度为87.50%,特异度为96.97%,准确度为93.88%,阳性预测值为93.33%,阴性预测值为94.12%,约登指数为0.845,曲线下面积(AUC)为0.943。结论MRE能够用于ITCL与IBCL的鉴别诊断,且具有较好的诊断效能。Objective To analyze the differential efficacy of MR enterography(MRE)in intestinal T-cell lymphoma(ITCL)and intestinal B-cell lymphoma(IBCL).Methods 98 patients with extranodal non-Hodgkin's lymphoma(NHL)admitted to our hospital from February 2020 to September 2022 were retrospectively analyzed.According to the results of pathological biopsy,they were divided into ITCL group(n=32)and IBCL group(n=66).The results of MRE examination were collected.The intestinal wall morphology,lesion location,other organ involvement,lesion enhancement mode,number of lesions and complications were compared between the two groups.The differences of MRE signs between ITCL and IBCL were analyzed,and the differential efficacy of MRE for ITCL and IBCL was analyzed.Results Among the 98 NHL patients,30 were diagnosed as ITCL by MRE and 68 were diagnosed as IBCL by MRE.Taking the pathological biopsy results as the"gold standard",the sensitivity,specificity,accuracy,positive predictive value,negative predictive value,Yoden index and area under curve(AUC)of MRE in differentiating ITCL and IBCL were 87.50%,96.97%,93.88%,93.33%,94.12%,0.845 and 0.943 respectively.Conclusion MRE can be used in the differential diagnosis of ITCL and IBCL,and it has good diagnostic efficacy.
