Quantitative maps of T1-shortening (ΔT1) related to intra-venous contrast media administration are obtained in patients with Multiple Sclerosis by using 3D Quantitative Transient-state Imaging. Statistically significant ΔT1 is observed not only in enhancing lesions, but also in some non-enhancing lesions, suggesting a potential role of this method as a quantitative imaging biomarker to detect subtle blood-brain barrier damage.
