AIM To measure the prevalence of abnormal rest perfusion in a population of consecutive patients with known hypertrophic cardiomyopathy (HCM) referred for cardiovascular MRI (CMR), and to assess any associations between abnormal rest perfusion and the presence, pattern, and severity of myocardial scar and the presence of risk factors for sudden death. … (More)
BACKGROUND Direct comparison of CT and magnetic resonance (MR) perfusion techniques has been limited and in vivo assessment is affected by physiological variability, timing of image acquisition, and parameter selection. OBJECTIVE We precisely compared high-resolution k-t SENSE MR cardiac perfusion at 3 T with single-phase CT perfusion (CTP) under… (More)
We present the results of transmural perfusion gradient (TPG) analysis (a novel method to evaluate the presence of subendocardial ischemia) versus fractional flow reserve (FFR) for the detection of hemodynamically significant coronary artery disease (CAD).
