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...
متن کاملQuantification of myocardial perfusion by cardiovascular magnetic resonance
The potential of contrast-enhanced cardiovascular magnetic resonance (CMR) for a quantitative assessment of myocardial perfusion has been explored for more than a decade now, with encouraging results from comparisons with accepted "gold standards", such as microspheres used in the physiology laboratory. This has generated an increasing interest in the requirements and methodological approaches ...
متن کاملQuantification of myocardial perfusion with self-gated cardiovascular magnetic resonance
BACKGROUND Current myocardial perfusion measurements make use of an ECG-gated pulse sequence to track the uptake and washout of a gadolinium-based contrast agent. The use of a gated acquisition is a problem in situations with a poor ECG signal. Recently, an ungated perfusion acquisition was proposed but it is not known how accurately quantitative perfusion estimates can be made from such datase...
متن کاملRapid ungated myocardial perfusion cardiovascular magnetic resonance: preliminary diagnostic accuracy
BACKGROUND Myocardial perfusion cardiovascular magnetic resonance (CMR) is a well-established method for detection of ischemic heart disease. However, ECG gating problems can result in image degradation and non-diagnostic scans, particularly in patients with arrhythmias. METHODS A turboFLASH saturation recovery pulse sequence was used without any ECG triggering. One saturation pulse followed ...
متن کاملCombined long- and short-axis myocardial perfusion cardiovascular magnetic resonance.
PURPOSE To date, myocardial perfusion cardiovascular magnetic resonance (CMR) has been reported in single and multiple short-axis slices. Three short-axis planes can assess 16 segments of the standard 17-segment myocardial model, but this approach fails to assess the ventricular apex that requires at least one long-axis plane. We therefore evaluated the feasibility and benefit of combined long-...
