Scatter plot shows the coronary enhancement ratio (CER) for patients with and without stenotic coronary arteries under adenosine stress. Horizontal lines are the same as in Fig. 1. On the iodine map (left), CER was significantly less for patients with stenotic coronary arteries than for those without them (* P < 0.0001). On the 120 kV images (right), there was no difference in CER between patients with and without stenotic coronary arteries. Pa patients
