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.
我们报告了一种新型微压计尖端导管，用于在完整动物模型的电影门控梯度回波核磁共振成像期间记录高保真压力。在测试用于其构造的各种金属和合金中，黄铜产生的核磁共振伪影最小且放大倍数最小。使用这种新的导管设计，成像期间几乎没有信号损失，心内膜边界也没有失真。
