Abstract

We used the arterial pressure wave as a reliable trigger to synchronize MR imaging to the cardiac cycle. Pressure readings and MR images remained undistorted using a conventional ferromagnetic micromanometer-tip catheter. As a safe alternative to triggering to ventricular pressure, this approach allows varying the time relation between the trigger and the cardiac cycle while maintaining the advantages of pressure-gating.

摘要

我们使用动脉压力波作为可靠的触发信号，使磁共振成像（MR）与心动周期同步。使用传统的铁磁性微测压头导管时，压力读数和MR图像不会失真。作为触发心室压力的安全替代方法，这种方法允许在保持压力门控优势的同时，改变触发信号与心动周期之间的时间关系。
