Fig. 12.
Examples of different MT contrasts acquired with a ZTE sequence. The ihMTR and ihMTRinv images show high sensitivity and specificity to myelin (Abbreviations: PDw – Proton Density weighted, T1w – T1 weighted, MTw – MT weighted, eMTw – enhanced MT weighted, with dual-sided saturation, MTR – Magnetization Transfer Ratio, eMTR – enhanced MT Ratio, ihMTR – inhomogeneous MTR, the difference between eMTR and MTR, ihMTRinv – inverse ihMTR using the T1w image as a reference instead of the PDw image).
