Patients were longitudinally evaluated by MRI, clinical examination, and nerve conduction studies at baseline and after 6 months.ResultsIn sciatic nerves of CIDP patients, mean cross-sectional area was significantly higher and fractional anisotropy value was significantly lower, compared to controls. In contrast, muscle proton-density fat fraction was significantly higher in thigh muscles of patients with CIDP, compared to controls. MRI parameters showed high reproducibility at baseline and 6 months.InterpretationAdvanced MRI parameters demonstrate subclinical proximal nerve damage and intramuscular fat accumulation in CIDP. Data suggest DTI and multiecho Dixon MRI might be useful in estimating axonal damage and neurogenic muscle changes in CIDP.}, cin = {INM-3}, ddc = {610}, cid = {I:(DE-Juel1)INM-3-20090406}, pnm = {572 - (Dys-)function and Plasticity (POF3-572)}, pid = {G:(DE-HGF)POF3-572}, typ = {PUB:(DE-HGF)16}, pubmed = {pmid:29376089}, UT = {WOS:000422664400003}, doi = {10.1002/acn3.502}, url = {https://juser.fz-juelich.de/record/841199}, }
