Native T1 mapping versus myocardial perfusion reserve index for coronary microvascular dysfunction detection in patients with ischaemia and nonobstructive coronary artery disease: positron emission tomography/magnetic resonance imaging validation.
AIM Native T1 mapping has not been systematically compared with the myocardial perfusion reserve index (MPRI) for detecting coronary microvascular dysfunction (CMVD) in patients with ischaemia and nonobstructive coronary artery disease (INOCA). The aim of this study was to investigate the diagnostic performance of nati...
