腹腔动脉、肠系膜上动脉主干的多层螺旋CT影像解剖学研究

摘要

Objective To explore the anatomic characters of celiac arteriogram (CA) and superior mesenteric artery with enhanced MSCTA scan. Methods 200 cases were treated with thin multiplane reformation (MPR), plane reorganization maximum intensity projection (MIP) and volume rendering (VR) method reconstruction to observe celiac arteriogram. Superior mesenteric artery open position relative to the spine, celiac arteriogram.superior mesenteric artery diameter, sagittal plane angle and the angle and two sagittal arterial openings in long body axis spacing. Results 200 cases of celiac artery, superior mesenteric artery all can clearly be shown and measuree. Conclusion Enhanced multislice CT scan can reflect celiac arteriogram. Superior mesenteric artery dissection details and relationship.%目的 采用多层螺旋CT增强扫描(MSCTA)了解腹腔动脉(CA)、肠系膜上动脉(SMA)主干的活体解剖情况,为影像学诊断及临床诊治提供影像解剖学资料.方法 选取符合条件的200例成人增强扫描于动脉期采集的客积数据,应用薄层横断性多平面重组(MPR)、最大密度投影(MIP)和客积重建(VR)法重建,观察CA、SMA主干相对于脊柱的开口位置,测量CA和SMA主干的直径、与矢状面夹角及与矢状面的夹角、两动脉开口在身体长轴线的间距,结果200例中CA、SMA主干均能清楚显示并测值.结论 多层螺旋CT增强扫描能反映CA、SMA主干的解剖细节和相互关系.
