【摘要】 MR小肠造影以其完全没有辐射、良好的软组织分辨率、能够清楚显示小肠腔内外情况而在临床上应用越来越多。作者介绍2种MR小肠造影方法:口服法MR小肠造影检查(MR enterography)和插管法MR小肠造影检查(MR enteroclysis),其中尤以口服法MR小肠造影简单、易行、无痛苦。用对比剂填充小肠、使小肠充分扩张是保证小肠造影取得成功的关键。作者经验是2.5%(等渗)甘露醇溶液为较理想的对比剂。简要归纳了一些常见小肠病变的MRI诊断要点并图示。更多还原

【Abstract】 MR Imaging of the small bowel can clearly show endoluminal,mural and extraluminal condition,meanwhile there is no radiation and good soft tissue resolution,thereby it is currently utilized more and more.Two MR imaging methods are MR enterography and MR enteroclysis,between them MR enterography is easier and no pain.It is the key to fulfill and dilate the lumen of small bowel with contrast medium.We prefer the 2.5% mannitol as the contrast medium.The MRI findings of various small bowel diseases are brief introduced.更多还原
