Dobutamine stress cardiovascular magnetic resonance at 3 Tesla
PURPOSE The assessment of inducible wall motion abnormalities during high-dose dobutamine-stress cardiovascular magnetic resonance (DCMR) is well established for the identification of myocardial ischemia at 1.5 Tesla. Its feasibility at higher field strengths has not been reported. The present study was performed to prospectively determine the feasibility and diagnostic accuracy of DCMR at 3 Te...
متن کاملFirst-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...
متن کاملClinical Applications for Cardiovascular Magnetic Resonance Imaging at 3 Tesla
Cardiovascular magnetic resonance (CMR) imaging has evolved rapidly and is now accepted as a powerful diagnostic tool with significant clinical and research applications. Clinical 3 Tesla (3 T) scanners are increasingly available and offer improved diagnostic capabilities compared to 1.5 T scanners for perfusion, viability, and coronary imaging. Although technical challenges remain for cardiac ...
متن کاملWaveguide Magnetic Resonance Imaging at 3 Tesla
Introduction. Waveguides have been successfully used to generate magnetic resonance images at 7 Tesla for whole-body systems [1]. From these results, it has been established that waveguides are only suitable for 7T systems with wide bores of al least 60 cm. This is mainly due to the cut-off frequency of the cylindrical waveguides used. To overcome this limitation a parallel-plate waveguide was ...
متن کاملHigh-dose dobutamine stress magnetic resonance perfusion imaging at 3.0 Tesla
Background Dobutamine stress magnetic resonance (DSMR-wall motion) has been established as a valuable tool for the detection of inducible wall motion abnormalities. Additional perfusion imaging during DSMR (DSMR-perfusion) was shown to improve sensitivity for the detection of myocardial ischemia. Current experience is based on 1.5T only, mainly due to insufficient image quality of steady state ...
