High-Pitch Thoracic CT With Simultaneous Assessment of Coronary Arteries: Effect of Heart Rate and Heart Rate Variability on Image Quality and Diagnostic Accuracy

Study Questions:

Using a high-pitch spiral image acquisition protocol for computed tomography angiography (CTA) and a dual-source system, what mean heart rate and heart rate variability (HRV) are required for diagnostic imaging of the coronary arteries simultaneously with thoracic CT for noncardiac purposes?
