Dual echo steady state (DESS) acquisitions can be utilized to acquire high-resolution, quantitative T2 maps in clinically feasible scan times, thus facilitating investigation of T2 properties of in vivo tissues. In this work we present the results of an initial investigation of DESS quantitative T2 mapping in the breast. DESS T2 maps are assessed in normal, benign and malignant in vivo breast tissue and measured T2 values are compared to those previously reported for tissues in the breast.
