Discrepancies between coronary CT angiography and invasive coronary angiography with focus on culprit lesions which cause future cardiac events.

• Compared to ICA, PR in CCTA may be cause of false positive lesion. • CCTA-related value including PR shows higher prediction power of MACE than ICA-related value. • PR reflects atherosclerotic burden that can be related to cardiac events. • PR in CCTA should be observed carefully, even if it is false positive.
