Magnetic resonance microscopy (MRM), suggested in the earliest papers on MRI, has always been limited by the low signal-to-noise ratio (SNR) resulting from the small voxel size. MRM has largely been enabled by the use of microcoils which provide the SNR improvement required to overcome this limitation. Concomitant with the small coils is a small field-of-view, which limits the use of MRM as a histological tool or for imaging large regions in general. This paper describes initial results in wide field-of-view MR microscopy using a large array of narrow, parallel coils, which provides an SNR enhancement as well as the ability to use parallel imaging techniques. Comparison images made between a volume coil and the proposed technique demonstrate reductions in imaging time of over 100 with no loss in SNR or resolution.
