Abstract
We report a new micromanometer-tip catheter to record high-fidelity pressures during cine-gated gradient echo NMR imaging in an intact animal model. Of the various metals and alloys tested for use in its construction, brass produced the smallest NMR artifact with minimal magnification. With the use of this new catheter design, there was little signal loss and no distortion of endocardial borders during imaging. © 1991 Academic Press, Inc.Keywords
