Официальное название
Application of the Inhomogeneous Magnetisation Transfer MRI (ihMT) Technique, a New Myelin-specific MRI Technique, in Multiple Sclerosis
Обзор
The development of in vivo biomarkers sensitive to myelin disruption represents a major clinical need to be able to monitor the demyelination processes as well as the effect of remyelinating therapies in multiple sclerosis. The investigators recently proposed a technique, derived from the conventional magnetisation transfer (MT): inhomogeneous Magnetisation Transfer (ihMT). In preliminary studies, this simple-to-implement and robust technique has shown great sensitivity for evaluating the demyelination processes. The goal of the project is to evaluate the ability of ihMT to measure and describe the spontaneous demyelination and remyelination processes involved in active lesions in a population of patients with MS at the the disease onset.
