This work describes a forced-current-excitation (FCE) bilateral breast coil, modified for the insertion of a 32-channel receive array for 1H imaging and spectroscopy at 7T. A previous design of the bilateral quadrature volume coil employed RF shielding which prevented the insertion of a receive array with the associated hardware and cabling. The modified bilateral coil uses twinaxial cable for the FCE-enabling quarter-wave transmission lines, allowing balanced signal transmission and eliminating the need for the shields. The results include uniform bilateral excitation, an increase in efficiency as compared to the shielded coil, and successful installation of the 32-channel receive array.
