The high resolution multinuclear imaging in animal study has been highly demanded to research cancer therapies, neurodegenerative diseases and metabolic disorders. Although dual-tuned RF coil provide anatomical and functional MRI without subjects repositioning issued from the use of two separate tuned RF coils, it causes SNR loss due to adding trap circuit or PIN diode. Against this reserved problems, we suggest the exchangeable single tuned RF coil configuration on the fixed couch frame without subjects repositioning in the study. We prepare a dual tuned RF coil and two single tuned RF coils as well as evaluate SNR of separate coils with scanned animal MR images.
