Abstract

Multidetector CT is an ideal tool for the diagnosis of acute and chronic mesenteric ischemia. Advanced CT scanners and expertise in three-dimensional imaging are becoming increasingly widespread, opening the door to new opportunities and challenges in the evaluation of patients suspected of having mesenteric ischemia. This article reviews contrast administration and image acquisition protocols, the anatomy of the mesenteric vasculature, the etiology of acute and chronic mesenteric ischemia, and CT findings diagnostic for these conditions.

摘要

多排螺旋CT是诊断急慢性肠系膜缺血的理想工具。先进的CT扫描仪和三维成像技术日益普及，为疑似肠系膜缺血患者的评估带来了新的机遇与挑战。本文回顾了对比剂注射和图像采集方案、肠系膜血管的解剖结构、急慢性肠系膜缺血的病因以及这些疾病的CT诊断表现。
