A system has been developed to enable the acqusition of 16-channel ¹³C data on a Philips Achieva 7T scanner. Radiofrequency mixers are used to convert the transmitted signal to ¹³C, and the received signal back to ¹H to be acquired by the host system's receiver. A 16-element unilateral breast coil has been developed, and data have been acquired that show a substantial SNR improvement from use of the array.
