Abstract: Objective The aim of this study is to verify the imaging effect of mouse specific radio frequency ( RF) coils on a 1. 5 T superconducting magnetic resonance imaging ( MRI) equipment and evaluate the scientific research application value of mouse specific RF coils. Method Scan 20 g KM mice, 200 g SD rat and model mice of scientific research diseases on the 1. 5 T superconducting MRI system with mouse specific RF coil to obtain MRI images of the head, spine and abdomen of mice. Result Through analysis and evaluation of the images, it is found that high-resolution and high contrast MRI images can be obtained by scanning on the 1. 5 T superconducting MRI system with mouse specific RF coil. Conclusion The use of mouse specific RF coil with 1. 5 T superconducting MRI system can serve scientific and preclinical research well.
