Heart rate adaptive maximal resolution cardiovascular magnetic resonance myocardial stress perfusion imaging at 3.0T

Heart rate adaptive maximal resolution cardiovascular magnetic resonance myocardial stress perfusion imaging at 3.0T

Background Myocardial perfusion cardiovascular magnetic resonance (CMR) with vasodilator stress has high diagnostic accuracy for detecting coronary artery disease (CAD). Current CMR perfusion pulse sequences use largely fixed acquisition parameters designed to acquire at least three slices every heart beat, optimized for the heart rates that typically occur during pharmacological stress. In pat...

Advanced cardiovascular magnetic resonance myocardial perfusion imaging: high-spatial resolution versus 3-dimensional whole-heart coverage.

First-pass myocardial perfusion cardiovascular magnetic resonance at 3 Tesla.

PURPOSE To test the feasibility of first-pass contrast-enhanced myocardial perfusion imaging at 3 Tesla and to evaluate the change in perfusion index between normal, remote and ischemic myocardium, we obtained perfusion index from healthy subjects and patients with coronary artery stenosis. MATERIALS AND METHODS First-pass contrast-enhanced perfusion imaging was performed on 12 patients and 3...

Vasodilator stress cardiovascular magnetic resonance imaging in post-orthotopic heart transplant recipients: evaluation of safety, hemodynamics, and myocardial perfusion

Background Long-term survival after orthotopic heart transplant (OHT) is limited by coronary allograft vasculopathy and its associated myocardial perfusion abnormalities. Little is known how post-OHT patients respond to vasodilator stress cardiovascular magnetic resonance imaging (vsCMR). This study aimed (1) to evaluate the safety and hemodynamic response of post-OHT patients undergoing vsCMR ...
