We describe an eight-channel, non-overlapping phased array coil designed for high resolution MRSI and parallel DWI of the brain at 3.0 T. The non-overlapping design is desirable for its high peripheral SNR and reduction in noise in parallel imaging. The combination of a capacitive bridging technique and the standard system preamps eliminate the crosstalk due to the mutual inductance inherent to the design. The expected SNR improvements are validated in vivo for the aforementioned applications through imaging studies conducted on five volunteers.
