Assessment of myocardial perfusion, for example, using MRI or single-photon emission CT, plays a pivotal role in the clinical management of patients with known CAD because revascularization is most beneficial in patients with more severe ischemia (3).However, our meta-analysis was designed to analyze noninvasive coronary angiography using CT versus MRI with ...References1.
