What this trial studies

This observational study involves patients undergoing routine MRI scans who will complete additional sequences to assess the impact of compressed sensing on MRI signal quality. Participants will receive standard MRI sequences along with four additional sequences that last a total of 25 minutes. The study aims to enhance the understanding of MRI imaging techniques, particularly in patients with multiple sclerosis and those requiring brain MRIs. The goal is to evaluate how these additional sequences can improve diagnostic capabilities.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 with multiple sclerosis or those needing a brain MRI who are at low risk for inflammatory CNS disease.

Not a fit: Patients who are pregnant, breastfeeding, or under legal protection measures may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved MRI imaging techniques, enhancing diagnostic accuracy for patients.

How similar studies have performed: While the approach of using compressed sensing in MRI is gaining traction, this specific evaluation is relatively novel and has not been extensively tested in similar studies.
