Specialized spin-echo-based sequences have been developed to perform MRE in patients with short T2* where traditional MRE fails. This work demonstrates that these sequences are able to salvage such exams by improving SNR and MRE inversion confidence to the levels of successful GRE MRE exams. Additionally, the stiffnesses calculated by spin-echo and spin-echo-echo-planar acquisitions are equivalent to each other.
