Figure 2: The operator interface and acquisition window of coronary CT combined with carotid-cerebrovascular angiography using the Flash Spiral mode. Data were acquired in a caudocranial direction from the aortic arch to the vertex, selecting 55% of the R–R interval as the start phase. An ultra-short imaging times allows depiction of the entire heart, neck and head with only 60 mL contrast medium volumes. Abbreviations: CT, computed tomography; CTA, computed tomography angiography; ECG, electrocardiogram.
