Custom-Fitted 16-Channel Bilateral Breast Coil

MR receive coils with a higher number of channels generate images with higher signal-to-noise ratio and allow for accelerated imaging. In 2009, we constructed a 16-channel fitted breast coil, compared it to a standard 8-channel coil, and demonstrated these improvements in vivo. Commercial 16-channel coils are now available, and are becoming the standard for breast MRI.

A 16-channel fitted phased-array breast coil that enables higher spatial-resolution MRI.  Post-contrast T1-weighted images in a patient with suspected ductal carcinoma in situ (DCIS) using this coil, acquired in 3 minute.  The resolution (pixel volume) is a factor of 10 smaller than most protocols, and clearly shows a vessel with 0.3 mm diameter (arrow).  Signal-to-noise ratio (SNR) maps show a 3-5x improvement across the breast compared with the standard 8-channel coils.
