To determine T2 values of the median nerve with TESS and
the numbers of fascicles with a PD-TSE-fat-sat in
healthy volunteers and patients with
carpal-tunnel-syndrome at 7-Tesla. Six volunteers and
three patients were included. Axial-PD-TSE-fat-sat and
axial-3D-TESS were performed. Two reader assessed T2
values and fascicles. Mean T2 values of patients were
significantly higher for the median nerve in comparison
to healthy subjects (P = 0.008) with an ICC of 0.97.
Median of fascicle count was 19 in all subjects with an
ICC of 0.81. Axial-PD-TSE-fat-sat and axial-3D-TESS
provides fast and reliable morphological and biochemical
assessment of the median nerve.
