2. Fig. 1 Flowchart of subject enrolment and study design.
Based on the predefined inclusion and exclusion criteria, 56 patients successfully underwent myocardial CTP and routine CCTA examination. The image quality and diagnostic performance were compared between CCTA from CTP and routine CCTA using on coronary angiography as the gold standard. CCTA = coronary CT angiography; ATP = adenosine triphosphate; CTP = CT perfusion.

3. Fig. 2
Example case 1.
A 67-year-old man with chest pain for 3 years underwent both routine coronary CT angiography (CCTA) and CT perfusion. Routine CCTA images (A) and single-phase CCTA images (B) both illustrate mixed plaque in the proximal segment of the left anterior descending branch and first diagonal (D1) (red arrows), with no significant difference in qualitative and quantitative quality. Stress dynamic CT perfusion (C) shows reduced perfusion in the anterior wall of left ventricle and inter-ventricular septum (black and white triangle). Coronary angiography (D) confirms the lesions showed by CCTA.

4. Fig. 3 ROC results analysis between SP-CCTA and routine CCTA.
Receiver-operating-characteristic (ROC) curves show the diagnostic performance comparison between SP-CCTA (solid line in blue) and routine CCTA (solid line in green). The area under the ROC curve for single phase-CCTA and routine CCTA were (95% CI, to 0.930) and (95% CI, to 0.932) for the diagnosis of stenosis of 50% or more on a per-vessel basis (A); (95% CI, to 0.917) and 0.843(95% CI, to 0.927) for the diagnosis of stenosis of 70% or more on a per-vessel basis (B); (95% CI, to 0.942) and (95% CI, to 0.958) for the diagnosis of stenosis of 50% or more on a per-segment basis (C); (95% CI, to 0.937) and (95% CI, to 0.952) for the diagnosis of stenosis of 70% or more on a per-segment basis (D). SP-CCTA = single-phase CCTA; R-CCTA = routine CCTA, other abbreviations as in Fig. 1.
