Abstract: This paper introduces the design and making of a surface coil for 23Na magnetic resonance imaging. A single-loop 23Na surface coil was made and used to acquire 23Na density-weighted images on tubes filled with NaCl solution, boiled salted quail egg and rat brain on a Bruker Biospec 47/30 MRI scanner. This study represents the first step towards having 23Na magnetic resonance imaging as a tool in various biomedical applications.

Key words: magnetic resonance imaging, surface coil, sodium, LC circuit
