Abstract:
A system and method for non-contrast enhanced pulmonary vein magnetic resonance imaging substantially suppresses the signal from cardiac tissue adjacent to the left atrium and pulmonary vein is provided. Significant conspicuity of the left atrium and pulmonary vein versus adjacent anatomical structures is produced. In this manner, more accurate measurements of pulmonary vein ostia size are facilitated, as well as more accurate registration of imaging volumes with a radiofrequency ablation catheter during pulmonary vein isolation procedures. In addition, more robust three-dimensional volume views of the left atrium and pulmonary vein are produced without the administration of contrast agents.
