Inhomogeneous magnetization transfer (ihMT) MRI is uniquely sensitive to myelin with lipids as a primary source of its contrast. In this study, we investigated whether ihMT can detect white matter structures in the hypomyelinated shiverer mouse brain, a model of dysmyelination. Conventional MT and ihMT images were acquired from ex vivo Rag2−/− control and shiverer mouse brains at 7 Tesla using previously reported optimized saturation parameters. ihMT ratio (ihMTR) maps revealed hypomyelinated corpus callosum in the shiverer mouse brain, whereas conventional MT ratio (MTR) maps showed no clear contrast. The ihMTR values of the corpus callosum in the shiverer mice were reduced by approximately 40% compared to controls, but remained significantly higher than the ihMTR values of the cortex. The finding further confirms ihMT’s high myelin specificity and suggests its use as a marker to detect early myelination or myelin repair.
