To evaluate non-inferiority of iterative-reconstruction-based coronary CT angiography for the short-term clinical impacts as compared with conventional coronary CT angiography
Efficacy
Confirmatory
Not applicable
Ratio of patients with non-significant coronary artery stenosis determined by catheter coronary angiography performed during 90-days follow-up periods after CT examination.
1. Rate of patients who undergo noninvasive coronary tests other than cCTA within 90 days from cCTA.
2. Radiation exposure for a coronary test:
(1) DLP, effective radiation dose for cCTA
(2) The estimated cumulative effective radiation dose for cCTA, stress SPECT, stress PET-CT, ICA and PCI at 90 days follow-up
3. The image quality of CCTA:
(1) Rate and causes of unevaluable cCTA
(2) objective image quality (noise, SNR, and CNR)
(3) subjective image quality using a 4-grade scale.
4. Rate of patients who do not undergo revascularization after ICA within 90 days from cCTA.
5. Major Adverse Coronary Event rates at 90 days, defined as the composite rate of all-cause death, acute coronary syndrome and unplanned hospitalization leading to urgent revascularization.
