摘要 目的:探讨MSCT对急性肠系膜缺血的诊断价值。方法:回顾性分析经手术或介入治疗证实的36例急性肠系膜缺血患者的CT表现。所有患者均行CT检查,包括平扫、增强扫描动脉期、增强扫描门脉期并进行血管重建。后处理采用容积显示技术(VRT)、多平面重组(MPR)和薄层最大密度投影(MIP)进行动脉和门脉成像。结果:肠系膜上动脉栓塞5例,肠系膜上动脉狭窄6例,肠系膜上静脉血栓形成25例。CT直接征象为血管内充盈缺损(30例)或狭窄(6例)。间接征象包括:肠管扩张、肠腔内积液积气(22例),肠壁增厚(14例),肠壁薄纸样改变(3例),肠壁积气(3例),肠系膜脂肪水肿及渗出(4例)。结论:MSCT与其三维重组技术相结合是诊断急性肠系膜缺血的一种有效且无创的影像检查方法,可以明确阻塞动脉的部位及范围,对手术有较高的指导价值。 Objective:To study the clinical value of multi-slice spiral CT(MSCT) in the diagnosis of acute mesenteric ischemia.Methods:The CT features of 36 patients with surgery/interventional therapy proved acute mesenteric ischemia were reviewed retrospectively.All patients underwent MSCT scanning,including plain scan,arterial phase and portal vein phase scanning after contrast administration.Post-processing techniques including volume rendering,multi-planar reformation and thin-section maximum intensity projection ...
