Objectives
Narrative objectives1
To examine the relationship between clinical outcomes following several interventions (medications, percutaneous coronary interventions, or coronary artery bypass grafting) and coronary plaque morphology detected on non-contrast T1 weighted magnetic resonance (T1WI).
Basic objectives2
Others
Basic objectives -Others
(A) To examine the clinical outcomes following plaque evaluation by T1WI in patients with coronary artery disease.
(B) To examine the relationships between coronary plaque morphology by T1WI and the occurrence of myocardial ischemia.
(C) To examine the predictive values of plaque evaluation by T1WI during percutaneous coronary intervention.
