In multiple sclerosis and other demyelinating disorders of the central nervous system assessment of change in myelin content would be an important clinical tool. Magnetization Transfer Ratio (MTR) is a semiquantitative MR technique for detecting macromolecules, like myelin. In this study we have developed a guided semi-automatic method for detecting regional MTR change in the mouse brain. By comparing MTR change to histopathology we show that MTR can detect myelin change in several regions of the mouse brain, including deep gray matter.
