Magnetization transfer imaging (MTI), an advanced MRI technique, is sensitive to disease in normal appearing white matter (NAWM) in patients with MS.<\/jats:p><jats:p> <jats:italic>Design\/Methods:<\/jats:italic> We tested if MTI detected subcortical (deep) gray matter abnormalities in patients with MS (<jats:italic>n<\/jats:italic>= 60) vs. age\u2010matched normal controls (NL, <jats:italic>n<\/jats:italic>= 20). Magnetization transfer ratio (MTR) maps were produced from axial proton density, conventional spin\u2010echo, 5 mm gapless slices covering the whole brain. Region\u2010of\u2010interest\u2013derived MTR histograms for the caudate, putamen, globus pallidus, thalamus, and NAWM were obtained. Whole brain MTR was also measured.<\/jats:p><jats:p> <jats:italic>Results:<\/jats:italic> Mean whole brain MTR and the peak position of the NAWM MTR histogram were lower in patients with MS than NL (<jats:italic>P<\/jats:italic> &lt; .001) and mean whole brain MTR was lower in secondary progressive (SP, <jats:italic>n<\/jats:italic>= 10) than relapsing\u2010remitting (RR, <jats:italic>n<\/jats:italic>= 50, <jats:italic>P<\/jats:italic> &lt; .001) patients. However, none of the subcortical gray matter nuclei showed MTR differences in MS vs. NL, RR vs. SP, or SP vs. NL.<\/jats:p><jats:p> <jats:italic>Conclusions:<\/jats:italic> The MTI technique used in this cohort was relatively insensitive to disease in the deep gray matter nuclei despite showing sensitivity for whole brain disease in MS. It remains to be determined if other MRI techniques are more sensitive than MTI for detecting pathology in these
