(A–D) Bi-component and single component T2* fitting results of two single fascicles (A, C) and two whole nerves which include these fascicles (B, D). (E–H) UTE bi-component T2* fitting and single component T2* fitting results from eight nerves. Totally 24 fascicles from 8 nerves were analyzed. fS, fraction of short T2* components (STCs); T2S*, T2* of the STCs; T2L*, T2*of the long T2* components.
