Derived from conventional magnetization transfer, inhomogeneous magnetization transfer (ihMT) has been shown to be a promising method for myelin imaging in recent studies. In the present study, the test-retest reproducibility and multi-site variability of ihMT in measuring major white matter fibers were evaluated. Good test-retest reproducibility and multi-site agreements were obtained. These findings support the use of ihMT measurements as biomarkers in multicenter and/or longitudinal studies.
