A dipole antenna achieves good isolation from a loop coil when it is located over the centre of a loop coil. Such an arrangement can be used as a dual-tuned coil, by tuning the dipole and the loop to the 1H and X frequencies, respectively. At 3 T, however, the length of a dipole antenna is too long to be of use for brain applications. In this study, we bent the dipole antenna around the head to overcome the length problem. We then evaluated the feasibility of combining two dipole antennae and a 4-loop array for 1H/31P application.
