A long axis view to demonstrate left ventricular regional wall motion was devised for the ultrafast CT scanner. The patients are positioned supine, head first, into the scanner. The scan table is slewed 20 degrees counter-clockwise in the horizontal plane without tilt. A bolus of contrast is injected via a median antecubital vein. Contiguous level R wave triggered cine studies are obtained during peak passage of contrast through the heart to image the entire left ventricular cavity. Fourteen patients had left ventricular wall motion compared by long axis CT and RAO 30 degrees single plane ventriculography at catheterization. In all cases, regional wall motion in comparable segments by both methods was in agreement. It is concluded that the ultrafast CT long axis view permits diagnosis of left ventricular regional wall motion abnormalities. This view images the apex and sections the interventricular septum and lateral free wall horizontally. Unlike conventional CT views, it is comparable to the RAO left ventriculogram.
为超快速CT扫描仪设计了一种用于显示左心室局部壁运动的长轴视图。患者仰卧，头部先进入扫描仪。扫描台在水平面逆时针旋转20度且无倾斜。通过肘正中静脉注射造影剂团注。在造影剂通过心脏的高峰期进行连续层面R波触发的电影研究，以成像整个左心室腔。14例患者在导管插入术时通过长轴CT和右前斜30度单平面心室造影对左心室壁运动进行了比较。在所有病例中，两种方法在可比节段的局部壁运动一致。结论是，超快速CT长轴视图可用于诊断左心室局部壁运动异常。该视图可对心尖成像，并水平剖切室间隔和外侧游离壁。与传统CT视图不同，它与右前斜位左心室造影相当。
