abstract = {Our aim was to assess the role of quantitative 1H and 23Na
MRI methods in providing imaging biomarkers of disease
activity and severity in patients with Facioscapulohumeral
muscular dystrophy (FSHD).We imaged the lower leg muscles of
19 FSHD patients and 12 controls with a multimodal MRI
protocol to obtain STIR-T2w images, fat fraction (FF), water
T2 (wT2), water T1 (wT1), tissue sodium concentration (TSC),
and intracellular-weighted sodium signal (inversion recovery
(IR) and triple quantum filter (TQF) sequence). In addition,
the FSHD patients underwent muscle strength testing.Imaging
biomarkers related with water mobility (wT1 and wT2) and ion
homeostasis (TSC, IR, TQF) were increased in muscles of FSHD
patients. Muscle groups with FF > $10\%$ had higher wT2,
wT1, TSC, IR, and TQF values than muscles with FF < $10\%.$
Muscles with FF < $10\%$ resembled muscles of healthy
controls for these MRI disease activity measures. However,
wT1 was increased in few muscles without fat replacement.
Furthermore, few STIR-negative muscles (n = 11/76) exhibited
increased wT1, TSC, IR or TQF. Increased wT1 as well as 23Na
signals were also present in muscles with normal wT2. Muscle
strength was related to the mean FF and all imaging
biomarkers of tibialis anterior except wT2 were correlated
with dorsal flexion.The newly evaluated imaging biomarkers
related with water mobility (wT1) and ion homeostasis (TSC,
IR, TQF) showed different patterns compared to the
established markers like FF in muscles of FSHD patients.
These quantitative biomarkers could thus contain valuable
complementary information for the early characterization of
disease progression.},
