磁共振小肠造影对小肠疾病的诊断价值

Value of magnetic resonance enteroclysis in the diagnosis of small intestinal diseases

目的 探讨磁共振小肠造影对小肠疾病的诊断价值。方法 对 2 1例疑为小肠疾病的患者行磁共振小肠造影检查 ,并与小肠插管造影和 (或 )手术病理结果比较。结果 2 1例行磁共振小肠造影检查的患者中 ,2 0例与小肠插管造影相符 ,包括克罗恩病 6例 ,小肠肿瘤 4例 ,肠梗阻 3例 ,肠结核 1例 ,十二指肠结肠瘘 1例 ,有 5例经各项检查均未发现小肠有明显病变。另 1例磁共振小肠造影诊断为克罗恩病 ,但小肠插管造影误诊为淋巴瘤。磁共振小肠造影与临床诊断符合率为 10 0 % ,而小肠插管造影为 95.2 %。有 8例行手术治疗 ,结果均与磁共振小肠造影表现相符 ,其中 7例与小肠插管造影相符。结论 磁共振小肠造影对小肠疾病 。

Objective To evaluate the role of magnetic resonance enteroclysis (MRE) in the diagnosis o f small intestinal diseases. Methods MRE findings in 21 cases of small intestinal diseases wer e compared with findings of conventional enteroclysis and/or surgery. Results MRE and conventional enteroclysis were identical in 20 of 21 cases, including Crohn disease in 6, intestinal neoplasms in 4, inte stinal obstruction in 3, intestinal tuberculosis in 1, duodenocolic fistula in 1 , and normal in 5. However, one patient with Crohn disease found by MRE was not diagnosed by conventional enteroclysis. The clinical diagnostic coincidence rat e of MRE was 100%, while that of conventional enteroclysis was 95.2%. MRE and su rgical diagnoses were same in 8 of 8 cases, while conventional enteroclys is and surgical diagnoses were same in 7 cases. Conclusions MRE is a valuable method in diagnosis of small intestinal diseases, especially t he diseases involving the bowel wall and extralumen.
