We constructed and tested a new multiple-animal magnetic resonance imaging (MRI) device that uses a 3-Tesla (3-T) whole-body scanner. An array coil comprising 16 small circular coils was connected to 16 preamplifiers and receivers of the scanner. This device can be used to perform simultaneous whole-body scanning of 4 rats or 16 mice. This approach facilitates progress in preclinical MRI and may be helpful in pharmaceutical drug-development studies in which various doses of multiple compounds are assessed in a large number of animals.
