Synopsis

Magnetization transfer (MT) has been conventionally used for the determination of myelin. However, the problem with the MT is that it reflects bound water that is not related to myelin. Inhomogeneous Magnetization Transfer (ihMT) can act specifically on myelin, it has been reported to be a useful method for quantifying myelin in brain and spinal cord regions. In this study, we compared conventional MT and ihMT for the brachial plexus, and ihMT might be able to reflect more accurate information about myelin than MT.
