<strong>Abstract</strong><br />

Background: The extent of iron deposition in the subcortical deep gray matter (SDGM) has<br />

been extensively investigated in adult but not in pediatric multiple sclerosis (MS) patients.<br />

Objective: To assess abnormal phase values, indicative of increased iron content, using<br />

susceptibility-weighted imaging (SWI)-filtered phase of the SDGM in pediatric MS patients and<br />

healthy controls (HC).<br />

Methods: Twenty (20) pediatric MS patients (11 female, 9 male) and 21 age- and sex-matched<br />

HC (10 female, 11 male) were scanned on a 3T GE scanner. Mean age was 15.6 (SD=2.9) years<br />

in patients, and 14.8 (SD=3) years in HC. Mean phase of the abnormal phase tissue (MP-APT),<br />

normal phase tissue volume (NPTV) and normalized volume measurements were derived for<br />

total SDGM, as well as specific structures separately. The study was approved by local<br />

Institutional Review Board and all participants provided written informed consent.<br />

Results: Significantly increased MP-APT (28.2%, p
