【摘要】：目的:比较多模态MR小肠口服造影法与CT小肠造影在诊断小肠肿瘤性疾病中的价值。方法:对本院2012年2月至2014年8月对怀疑有小肠肿瘤的65例患者行CT和多模态MR小肠造影检查。由两位腹部影像学医师分别对CT及MR图像进行分析,记录十二指肠、近段空肠、远段空肠、近段回肠以及远段回肠肠管的病变累及情况,并与手术以及内镜活检病理结果进行对照。结果:经手术及内镜病理证实,65例中共37例患者有38个小肠肿瘤病灶(腺癌6例,淋巴瘤7例,间质瘤18例,神经内分泌肿瘤3例,海绵状血管瘤2例,脂肪瘤2例)。CT及MRI对小肠肿瘤性病变的检出率分别为97.4%(37/38)和94.7%(36/38);McNemar检验结果显示,CT小肠显像与多模态小肠MR口服造影法对于多部位侵犯的小肠肿瘤性病变的诊断敏感度和特异度的差异无统计学意义(P0.05)。两例黏膜海绵状血管瘤伴出血仅在CT图像上显示。结论:多模态MR小肠口服造影法与CT小肠造影均是诊断小肠肿瘤性疾病的有效手段。
[Abstract]:Objective: to compare the value of multimodal Mr enterography and CT enterography in the diagnosis of small intestinal neoplasms. Methods: from February 2012 to August 2014, 65 patients with suspected small intestinal tumors were treated with CT and multiple models. The CT and Mr images were analyzed by two abdominal radiographers. The pathological changes of duodenum, proximal jejunum, distal jejunum, proximal ileum and distal ileal duct were recorded. Results: there were 38 small intestinal tumor lesions (adenocarcinoma 6 cases lymphoma 7 cases stromal tumors 18 cases neuroendocrine tumors 3 cases). 2 cases of cavernous hemangioma, The diagnostic sensitivity of CT and MRI for small intestinal neoplasms were 97.437 / 38 and 94.736 / 38 / 38 respectively. The sensitivity of CT small bowel imaging and multimodal small intestinal Mr oral Mr imaging for the diagnosis of multi-site invasion of small intestinal neoplasms was demonstrated by McNemar test. Two cases of mucosal cavernous hemangioma with hemorrhage were only displayed on CT images. Conclusion: both multimodal Mr enterography and CT enterography are effective methods for diagnosis of small intestinal neoplasms.
