Magnetic resonance imaging provides structural and functional cardiovascular information with excellent soft tissue contrast. Real-time magnetic resonance imaging can guide transcatheter cardiovascular interventions in large animal models and may prove superior to x-ray and adjunct modalities for peripheral vascular, structural heart, and cardiac electrophysiology applications. We describe technical considerations, preclinical work, and early clinical studies in this emerging field.
磁共振成像能够提供具有出色软组织对比度的心血管结构和功能信息。实时磁共振成像可在大型动物模型中指导经导管心血管介入治疗,对于外周血管、心脏结构和心脏电生理应用而言,可能优于X射线及辅助方式。我们描述了这一新兴领域的技术考量、临床前研究工作以及早期临床研究。
