Two-dimensional Fast Spin Echo is a workhorse of clinical MRI. However, its minimum TE is in the order of milliseconds or tens of milliseconds, which limits its ability to image tissues with short T2*. This work aims to optimize the multi-echo ultra-short echo time (UTE) sequence to (i) visualize, (ii) generate an associated quantitative map of tissues with short T2*, and (ii) to produce CT-like images of bony structures, which often are not visible in clinical images routinely acquired using FSE sequence.
