The use of T2 mapping in the breast is currently limited by prohibitively long acquisition times. We present here a compressed sensing approach and show that we are able to acquire T2 mapping breast images with 5-fold acceleration relative to a fully sampled, multi spin echo sequence. This reduction in acquisition time may make T2 mapping a feasible option for quantitative imaging of the breast, particularly for longitudinal studies such as those evaluating treatment efficacy and response.
