MRI cardiovascular catheterization applications

在过去的一年里，我们继续我们的工作，应用快速核磁共振来指导简单和复杂的机械和生物干预。 我们继续使用MRI插管作为NIH临床中心的标准临床实践，这是基于我们早期对成人常规X光和完全MRI引导的经股动脉插管进行仔细的先导性研究比较。我们继续增强MRI插管的能力，以表征患者的心功能。我们已经在北美和欧洲的24个医疗中心通过在NIH的实验室举办实践研讨会来教授如何采用这些技术。 我们在0.55T下使用新型低场高性能心血管磁共振系统进行了人体心血管导丝插管。 我们继续重新调整用途并开发专门制造的MRI导管设备。 总体而言，我们已经成功地开发了用于心血管治疗的实时核磁共振的新应用，并继续建立在这些令人兴奋的新开发的临床应用上。

During the past year we have continued our work applying rapid MRI to guide simple and complex mechanical and biological interventions. We continue to employ MRI catheterization as standard clinical practice at the NIH clinical center, based on our earlier careful pilot research comparison of conventional X-ray and wholly MRI guided transfemoral pulmonary artery catheterization in adults. We continue to enhance the capabilities of MRI catheterization to characterize heart function in patients. We have taught two dozen medical centers across North America and Europe how to adopt these techniques by hosting hands-on workshops in our labs at NIH. We performed human cardiovascular guidewire catheterization using the new low-field and high-performance cardiovascular MRI system at 0.55T. We continue to repurpose and develop purpose-built MRI catheter devices. Overall we have successfully developed novel applications of real-time MRI for cardiovascular treatments, and we continue to build on clinical applications of these exciting new developments.
