Purpose To investigate practical methods for achieving routine simultaneous 2D MRI of multiple animals in large‐bore experimental scanners. Materials and Methods Three four‐element array geometries were compared against a standard single‐coil configuration in terms of image quality, ease of use, and data efficiency using a four‐channel, 4.7 T small animal imaging system. Results A linear arrangement of volume resonators permits unobstructed animal preparation and use of an imaging protocol that is almost identical to the single‐coil configuration without requiring any image correction or other additional postprocessing. Resulting in vivo images were visually indistinguishable from those acquired through the single‐coil configuration. Conclusion The efficiency of animal studies employing 2D MRI techniques can be substantially improved by using a linear array of commercially available resonators. J. Magn. Reson.
