There has been a significant increase in carbon-13 and sodium-23 MRI research over the last decade, both in the areas of technical development and clinical applications. However, the lack of whole-body transmit systems for these nuclei limits large field of view imaging and uniform excitation. Here we demonstrate the imaging of natural abundance sodium and carbon signal from the abdomen using a 50 cm long 4-rung birdcage (40 cm inner bore) for abdominal 23Na/13C MRI. This whole body 23Na/13C coil has the potential to be used for a wide range of clinical applications.
