Adenosine Stress Cardiovascular Magnetic Resonance With Variable Density Spiral Pulse Sequences Accurately Detects Coronary Artery Disease: Initial Clinical Evaluation

摘要

BackgroundAdenosine stress CMR perfusion imaging can be limited by motion-induced dark-rim artifacts (DRA), which may be mistaken for true perfusion abnormalities. A high-resolution variable-density spiral (VDS) pulse sequence with a novel density compensation strategy has been shown to reduce DRA in first-pass perfusion imaging. We aimed to assess the clinical performance of adenosine stress CMR using this new perfusion sequence to detect obstructive coronary artery disease (CAD).
