title: Role of magnetic resonance spectroscopy in diagnosis and management of multiple sclerosis.
abstract: Application of magnetic resonance spectroscopy (MRS) to study the nature, pathogenesis, tissue injury and therapeutic response of MS patients has altered our view of multiple sclerosis (MS) fundamentally. By offering biochemical analysis of demyelinating lesions and axonal injury, MRS generates objective and quantifiable data on central nervous system tissue and metabolism during pathogenesis of MS. Of these biochemical markers, N-acetylaspartate, which serves as an indicator of neuronal and axonal injury and choline (Cho) peaks which demonstrate cell membrane metabolism, provide a plethora of data on the neuropathology of MS. Based on these findings, MRS provides neuroscientists with a unique diagnostic and prognostic tool to follow MS patients and assess their response to treatment with immunomodulators. MRS findings are so significant that consideration should be given to their routine inclusion as secondary outcome measures in clinical trials of MS patients.
