SC#4 – Pathological SC MR investigations


Research Works

New protocols including anatomical and parametric MRI (morphometry, DTI, MT/ihMT, T1 mapping) are investigated on both high and ultra-high field MR systems in order to better characterize human SC pathologies, in terms of diagnostic, prognostic and evaluation of the potential recovery.

Current investigations more particularly concern cervical myelopathy (CSM), as well as amyotrophic lateral sclerosis (ALS) and multiple sclerosis (MS).

Recent results demonstrated the added values of ihMTR (inhomogeneous magnetization transfer ratio) in demyelinating pathologies such as MS, strong atrophy (Cross Sectional Area measurements, CSA) in ALS, as well as great potential of MP2RAGE acquisitions in the detection of MS lesion.

             Improved SC lesion detection in MS using 3T MP2RAGE (from Demortière et al., 2020)
