To evaluate longitudinal changes in venous oxygenation
(Yv) from superior sagittal sinus in multiple sclerosis
(MS), 17 patients underwent
T2-relaxation-under-spin-tagging imaging at an interval
of 2 years. Twenty-one controls were also included.
Significantly elevations in CPMG-T2 (68.2410.64ms vs
59.657.13ms, p=0.01) and Yv (62.16.25% vs 58.24.08%,
p=0.03) were observed from MS patients compared to
healthy controls. Compared to baseline, a significant
increase in CPMG- T2 was observed at follow-up time
point (68.2410.64ms vs. 95.4618.46ms). Similarly, a
significant increase in Yv was observed at follow-up
(62.16.25% vs. 74.826.51%). TRUST may be a useful
technique for assessing longitudinal variations in Yv in
MS.
