What this trial studies

This observational study aims to assess how gadolinium injection affects the measurement of quantitative susceptibility mapping (QSM) signals in patients with white matter disease. Participants will undergo MRI scans both with and without gadolinium injection, as part of their standard care, and will complete a questionnaire regarding their previous exposure to gadolinium. The study will help determine the influence of gadolinium on MRI results, which could improve diagnostic accuracy for inflammatory CNS pathologies.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 with inflammatory CNS pathology who require an MRI with gadolinium injection as part of their care.

Not a fit: Patients who are pregnant, breastfeeding, or have had more than three gadolinium MRI exams in their lifetime may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the understanding of MRI signal changes due to gadolinium, leading to better diagnostic practices for patients with white matter disease.

How similar studies have performed: While there may be studies assessing gadolinium's effects, this specific approach to measuring QSM signals is novel and not widely tested.
