Summary: Parallel Imaging for NMR Microscopy at 14.1 Tesla

Parallel imaging techniques using arrays of mutually decoupled
coils have become standard on almost all clinical imaging sys-
tems. Such techniques also have great potential for high-field
magnetic resonance (MR) microscopy, where measurement
times are usually long and susceptibility artifacts can be severe.
However, it is technically very challenging to design efficient
high-frequency phased arrays for small-diameter, vertical-bore
magnets, especially since standard decoupling methods, such
as impedance mismatched preamplifiers, cannot be easily in-
tegrated. A four-coil phased array was constructed for micro-
imaging at 600 MHz, and sensitivity encoding (SENSE) and
generalized autocalibrating partially parallel acquisitions
(GRAPPA) reconstructions of spin-echo and echo-planar im-
ages of the mouse brain were performed to reduce imaging
time and susceptibility artifacts, respectively. Magn Reson
