Abstract：Ischemia with non-obstructive coronary artery disease(INOCA)is characterized by coronary microvascular dysfunction and epicardial vasospasm as its core pathological mechanisms,which significantly increase the risk of adverse cardiovascular events.Non-invasive imaging modalities,including cardiac magnetic resonance imaging,myocardial computed tomography perfusion imaging,echocardiography,and positron emission tomography,have demonstrated significant potential in the evaluation of INOCA.Artificial intelligence further enhances the efficiency and accuracy of imaging-based assessments.This article provides a systematic review of the pathophysiological mechanisms underlying INOCA and recent advances in imaging techniques for its evaluation,with a focus on clinical applicability and technological innovation.
