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.
