WebSep 19, 2024 · The net magnetization vector in MRI is the summation of all the magnetic moments of the individual hydrogen nuclei. In the absence of an external magnetic field, the individual magnetic moments are randomly oriented and since they are in opposition, the net magnetization vector is considered to be zero. If hydrogen nuclei are placed within a ... WebConclusions: Magnetization transfer ratio is a novel imaging marker that quantifies macromolecular nerve changes in SMA 3, and positively correlates with clinical scores and CMAPs. Keywords: electrophysiology; magnetization transfer contrast (MTC) imaging; magnetization transfer ratio (MTR); neurodegeneration; spinal muscular atrophy (SMA).
