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.
