A dedicated radio frequency coil design for MR mammography needs to optimize sensitivity, reduce scan time, and improve patient comfort to ultimately facilitate diagnosis. We investigate signal-to-noise ratio and parallel imaging performance differences between widely used commercial 16-/18-channel receive coils for breast MRI at 3 T in prone and supine position and an in-house developed 28-channel wearable coil array (“BraCoil”). An SNR gain of up to a factor of 6 with BraCoil was found in this phantom study.
