In this work, we examine an approach using one or more dual echo multi-slice acquisitions that are themselves then repeated and combined. Between-slice motion is then estimated and the multiple echoes combined, allowing 3D mapping of T2* values in the presence of fetal head motion. We applied the methods to a cohort of healthy fetuses from mid-gestation onwards. This importantly provides a full 3D image and extends previously published measurements below 26W into the 20-26W period where many clinical MRIs are acquired after an earlier ultra-sound evaluation of pregnancy.
