多排螺旋CT小肠造影在评估小肠克罗恩病中的应用

Application of MSCT enterography in the evaluation of Crohn’s disease

对于消化科和放射科医师而言,评估小肠病变向来都是一项巨大的挑战.传统的放射影像学和内镜学方法常常受到肠管长度及内径宽度的限制.CT小肠造影是一种由传统CT技术改进而来的具有极高时间和空间分辨率的新兴技术,其优势在于能够优化对小肠肠管的显示和评估.如我们所知,克罗恩病是一种可以累及整个消化系的炎性病变,典型的克罗恩病常表现为肠道多节段性的、透壁性受累,而末端回肠常为其最易发部位.克罗恩病患者往往能很好地耐受CT小肠造影检查,而CT小肠造影检查常常能够对克罗恩病患者的小肠肠壁或周围器官产生的病理变化进行准确、高效的评估.本文将论述CT小肠造影检查的基本原则与他在评估小肠克罗恩病及其并发症中的应用.

The assessment of small bowel abnormalities has always been a challenging task for radiologists and gastroenterologists. Conventional radiologic and endoscopic evaluations are often limited by the length and caliber of small bowel loops. CT enterography, a robust new method with high spatial and isotropic spatial resolution, is a variant of conventional CT technique optimized for the evaluation of the small bowel. Crohn’s disease is an in？ammatory disease which can involve different areas of the gastrointestinal tract, and it was characterized by segmental and transmural in？ammation, with the terminal ileum being the most common site of involvement. CT enterography is well tolerated by these patients and enables accurate, efficient assessment of lesions arising from the small bowel wall or surrounding organs. In this article, we discuss the principle of CT enterography and its use in the evaluation of Crohn’s disease.
