This work presents a novel dual resonant breast coil design for combined sodium and proton breast MRI with increased SNR. The coil consists of a 7-channel sodium receive phased array, a large sodium transmit coil, and a 4-channel hydrogen transceive array. A coil layout with intersecting sodium and proton elements to decrease sodium shielding effects is also demonstrated. The new phased array coil demonstrates a 2-5x improvement in SNR for sodium imaging when compared to a simple single-loop dual resonant design. Improved sodium SNR will potentially enable better assessment of small breast lesions and more accurate measures of tissue.
