In order to take advantage of the sensitivity that high fields offer we have developed and describe here a 4-element receive-only array design for parallel imaging of the mouse brain at 14 T. To achieve the necessary decoupling between array elements we designed and built small, low noise and low input impedance preamplifiers which can fit in the limited diameter of the vertical bore magnet.
