We have designed and fabricated a new 32 channel ultra-high resolution 3T breast imaging coil array which enables spatial resolution approaching that of X-ray. The new coil permits acceleration factors of 16 or more and full bi-lateral coverage of the breasts with an isotropic resolution down to 0.3 mm. In this study, benchmark comparisons were made with a commercially available 7 channel breast array. The 32-channel coil provided increased speed and resolution for DWI, T1-weighted and T2-weighted images in phantoms and human volunteers.
