In this work, we improve upon previously reported values of T1 and T2* for sodium in the breast. Previously, we used a DESPOT1 sequence, whereas we have developed an inversion recovery sequence so that we can measure T1 values more accurately. For our healthy woman volunteer, we measured sodium T1 to be 39.0 4.8 ms, T2long to be 21.0 5.6 ms, and T2short to be 0.8 0.4 ms.
