Demyelination assessment with MRI for multiple sclerosis (MS) is a reliable biomarker for monitoring disease progression. Recently, inhomogeneous magnetization transfer (ihMT) combined sequencing has been developed for myelin-specific imaging. The purpose of this study was to evaluate ihMT in delineating MS lesions in the spinal cord by comparing the conventional imaging methods. The lesion-to-white matter contrast-to-noise ratio (CNR) on ihMT was significantly higher than the other methods. The qualitative analysis revealed clarity of lesion detection, but false positives were a concern. Our results in MS patients suggest that ihMT may be a helpful sequence for lesion detection.
