摘要
目的:探讨MRI多序列联合检查对炎症性肠病(IBD)的诊断价值。方法:选取2022年1月—2024年12月赣州市人民医院收治的66例疑似IBD患者。所有患者均接受MRI多序列检查。以内镜下黏膜活检的组织病理学检查结果为“金标准”,分析MRI多序列单独及联合检查诊断IBD的价值及其与病理检查结果的一致性。结果:66例疑似IBD患者经病理检查证实为IBD有59例(89.39%),其中溃疡性结肠炎(UC)27例(40.91%),克罗恩病(CD)32例(48.48%)。MRI多序列联合检查诊断IBD的敏感度和准确度均高于各序列单一检查,阴性预测值高于T_(1)WI序列、T_(2)WI序列(P<0.05)。Kappa检验显示,T_(1)WI序列、T_(2)WI序列诊断IBD的结果与病理结果的一致性不佳,增强扫描、弥散加权成像(DWI)诊断结果与病理结果的一致性一般,MRI多序列联合检查诊断结果与病理结果的一致性良好(P<0.05)。结论:MRI多序列联合检查能够准确诊断IBD,与病理结果的一致性良好。
Objective:To explore the diagnostic value of MRI multi-sequence combined examination in inflammatory bowel disease(IBD).Method:A total of 66 suspected IBD patients admitted to Ganzhou People's Hospital from January 2022 to December 2024 were selected.All patients underwent MRI multi-sequence examination.Taking the histopathological examination results of endoscopic mucosal biopsy as the"gold standard",the value of MRI multi-sequence alone and combined examination in the diagnosis of IBD and its consistency with the pathological examination results were analyzed.Result:Among the 66 suspected IBD patients,59 cases(89.39%)were confirmed as IBD by pathological examination,including 27 cases(40.91%)of ulcerative colitis(UC)and 32 cases(48.48%)of Crohn's disease(CD).The sensitivity and accuracy of MRI multi-sequence combined examination in the diagnosis of IBD were both higher than those of single examination of each sequence,and the negative predictive value was higher than that of T_(1)WI sequence and T_(2)WI sequence(P<0.05).Kappa test showed that the results of T_(1)WI sequence and T_(2)WI sequence in the diagnosis of IBD were not good consistent with the pathological results,the results of enhanced scanning and diffusion weighted imaging(DWI)were generally consistent with the pathological results,and the results of MRI multi-sequence combined examination was good consistent with the pathological results(P<0.05).Conclusion:MRI multi-sequence combined examination can accurately diagnose IBD and has good consistency with pathological results.
