Ultrafast (Cine) CT scanning provides cross-sectional millisecond tomography, and therefore combines digital imaging and high resolution without the need for either cardiac catheterization or any form of ECG gating. Fifty millisecond multilevel scanning at rates of 17 scans per second allows quantitation of left ventricular (LV) function at each tomographic level during a cardiac cycle. Calculations of global and regional ejection fraction can be obtained, and in addition ultrafast CT also has the potential for providing unique data concerning regional wall thickening, mass and even regional myocardial perfusion. Interventional studies with exercise and pharmacological agents have commenced and are currently being evaluated.
超速（电影）CT扫描提供横断面毫秒级断层扫描，因此无需进行心导管检查或任何形式的心电图门控，就能将数字成像与高分辨率相结合。以每秒17次扫描的速度进行50毫秒的多级扫描，可在心动周期内对每个断层水平的左心室（LV）功能进行定量分析。可以获得整体和局部射血分数的计算结果，此外，超速CT还有潜力提供有关局部心肌增厚、质量甚至局部心肌灌注的独特数据。关于运动和药物制剂的介入性研究已经开始，目前正在进行评估。
