2D non-slice selective UTE imaging of a bovine brain extract powder phantom with TEs of 8 μs (A), 0.1 ms (B), 0.2 ms (C), 0.3 ms (D), 0.4 ms (E) and 0.8 ms (F), as well as single-component exponential signal decay fitting of UTE images which shows a short T2* of 167±7 μs (G), and UTE phase imaging (H). Phase contrast can be generated for myelin lipid protons in bovine brain extract power despite of its extremely short T2* relaxation time.
