小肠是胃肠道最长的器官,因其走行弯曲,肠管常互相重叠,传统的胃肠道和内镜检查单纯地观察消化道腔内结构,尚不能很好显示肠壁和腔外结构.多层螺旋CT(MSCT)和磁共振成像(MRI)具有快速扫描和三维后处理能力,能清晰反映肠壁和肠腔外的病变.新的影像技术CT小肠灌肠造影(CTE)、MR小肠灌肠造影(MRE)具有良好的软组织对比度及三维成像能力,不仅可以观察黏膜,同时能够分析肠管周围的改变,提高了人们对小肠疾病影像诊断的认识.本文就近年来小肠疾病影像学诊断的进展及今后努力的方向作一述评.
The small intestine is the longest organ of the gastrointestinal tract, because of its bending curve, intestines often overlap each other, traditional gastrointestinal and endoscopic simple observation of the digestive tract cavity structure, the intestinal wall and extraluminal structure is not yet well displayed. Multi-slice spiral CT (MSCT) and magnetic resonance imaging (MRI) with fast scanning and three-dimensional post-processing capabilities, can clearly reflect the intestinal wall and intestinal lesions outside the new imaging technology CT small bowel enema (CTE), MR small intestine enema MRE has good contrast and three-dimensional soft tissue imaging ability, not only to observe the mucosa, but also to analyze the changes around the intestine and improve people’s awareness of small intestinal disease imaging diagnosis.In this paper, the progress of imaging diagnosis of small intestinal diseases in recent years and in the future Efforts to make a comment on the direction.
