abstract = {Multiple sclerosis (MS) is a demyelinating disorder of the
central nervous system (CNS). However, there is increasing
evidence of peripheral nerve involvement. This study aims to
characterize the pattern of peripheral nerve changes in
patients with newly diagnosed MS using quantitative magnetic
resonance (MR) neurography.In this prospective study, 25
patients first diagnosed with MS according to the revised
McDonald criteria (16 female, mean age = 32.8 ± 10.6 years)
and 14 healthy controls were examined with high-resolution
3-T MR neurography of the sciatic nerve using diffusion
kurtosis imaging (DKI; 20 diffusional directions, b = 0,
700, 1200 s/mm2 ) and magnetization transfer imaging (MTI).
In total, 15 quantitative MR biomarkers were analyzed and
correlated with clinical symptoms, intrathecal
immunoglobulin synthesis, electrophysiology, and lesion load
on brain and spine MR imaging.Patients showed decreased
fractional anisotropy (mean = 0.51 ± 0.04 vs. 0.56 ± 0.03,
p < 0.001), extra-axonal tortuosity (mean = 2.32 ± 0.17 vs.
2.49 ± 0.17, p = 0.008), and radial kurtosis (mean = 1.40
± 0.23 vs. 1.62 ± 0.23, p = 0.014) and higher radial
diffusivity (mean = 1.09 ∙ 10-3 mm2 /s ± 0.16 vs. 0.98 ±
0.11 ∙ 10-3 mm2 /s, p = 0.036) than controls. Groups did
not differ in MTI. No significant association was found
between MR neurography markers and clinical/laboratory
parameters or CNS lesion load.This study provides further
evidence of peripheral nerve involvement in MS already at
initial diagnosis. The characteristic pattern of DKI
parameters indicates predominant demyelination and suggests
a primary coaffection of the peripheral nervous system in
MS. This first human study using DKI for peripheral nerves
shows its potential and clinical feasibility in providing
novel biomarkers.},
