We demonstrate the combination of a magnetization transfer (MT) preparation pulse and a zero TE (ZTE) imaging data acquisition. This work shows the potential for a MR ratio (MTR) imaging of white mater disease using an intermittent MT preparation pulse to reduce SAR and scan time. The ZTE acquisition enables visualization of short T2 species while providing the benefit of low acoustic noise to improve patient comfort.
