In this study, a novel coil design, subsequently referred to as the rat brain coil, is described which exploits and combines the strengths of both solenoids and surface coils into a simple, multi-channel, receive-only coil dedicated to whole-brain rat imaging on a 3.0 T clinical MR scanner. Compared to other coils, the rat brain coil improved SNR by a minimum of 60%. Improvement in SNR afforded by the rat brain coil may broaden applications and experiments that utilize clinical MR scanners for in vivo image acquisition.
