Cardiovascular MR imaging: pressure-gating using the arterial pressure signal from a conventional ferromagnetic micromanometer-tip catheter.

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.
