摘　　要：急性肠缺血是指因肠壁缺血乏氧,最终发生梗死的一种疾病。由于早期发病症状不明显且无特异性,此病的死亡率一直保持在50%-70%,早期明确缺血的严重程度并施以治疗对于患者的生存是十分重要的。随着影像技术的不断发展,腹部电子计算机断层摄影(computer tomography,CT),超声检查以及数字减影血管造影(digital subtraction angiography,DSA)在诊断肠缺血中起着重要作用。近年来磁共振发展迅速,各种新技术的应用以及高分辨率成像使磁共振检查在显示缺血肠壁以及定量评估缺血的严重程度方面具有重要意义。作者主要对弥散加权成像、对比剂增强成像、分子影像技术、血流定量成像以及血氧定量成像评估急性肠缺血的研究进展进行综述。acute intestinal ischemia is a disease in which ischemia and hypoxia in the intestinal wall eventually result in infarction.Since the early onset symptoms are not obvious and non-specific,the mortality rate of this disease has been maintained at 50%-70%.It is very important for the survival of patients to determine the severity of ischemia in early stage and give treatment.With the continuous development of imaging technology,computer tomography(CT),ultrasound and digital subtraction angiography(DSA)have played an important role in the diagnosis of intestinal ischemia.In recent years,magnetic resonance imaging has developed rapidly.With the application of various new techniques and high resolution imaging,magnetic resonance examination is of great significance in displaying the ischemic intestinal wall and quantitatively evaluating the severity of ischemia.This article mainly reviews the progress of diffusion weighted imaging,contrast-enhanced imaging,molecular imaging,quantitative blood flow imaging and quantitative blood oxygen imaging in the evaluation of acute intestinal ischemia.
