abstract = {BackgroundDiagnosis and disease monitoring of non-systemic
vasculitic neuropathy (NSVN) are based on
electrophysiological and clinical measures. However, these
methods are insensitive to detect subtle differences of
axonal injury. We here assessed the utility of a
multiparametric MRI protocol to quantify axonal injury and
neurogenic muscle damage in NSVN.MethodsTen NSVN patients
and ten age-matched controls were investigated in this
single-center prospective study. All participants were
assessed by diffusion tensor imaging (DTI) of the tibial
nerve and multiecho Dixon MRI of soleus and gastrocnemius
muscles. These data were correlated with clinical and
electrophysiological data.ResultsDTI scans of the tibial
nerves of patients with NSVN showed significantly lower mean
fractional anisotropy (FA) values (0.32 ± 0.02)
compared to healthy controls (0.42 ± 0.01). FA values
of NSVN patients correlated negatively with clinical
measures of pain. Multiecho Dixon MRI scans revealed
significantly higher intramuscular fat fractions in the
soleus muscle $(19.86 ± 6.18\%$ vs.
$5.86 ± 0.74\%,$ p = 0.0015) and gastrocnemius
muscle $(26.09 ± 6.21\%$ vs. $3.59 ± 0.82\%,$
p = 0.0002) in NSVN patients compared to healthy
controls.ConclusionOur data provide a proof of concept that
MRI can render information about nerve integrity and muscle
pathology in NSVN. Further studies are warranted to evaluate
DTI and multiecho Dixon MRI as surrogate markers in NSVN.},
