> This page provides an overview of the role of Magnetic Resonance Imaging (MRI) in diagnosing and monitoring Multiple Sclerosis (MS), including technical explanations, imaging techniques, and their importance in disease management.

## Details
- [Best View Inside: MRI Reveals MS Lesions](#): MRI is used to detect MS lesions and assess disease activity during diagnosis and follow-up.
- [Cross-sectional Images of the Brain](#): MRI produces detailed, painless images of brain and spinal cord tissues, differentiating fresh inflammation from older scars.
- [What Are MS Lesions?](#): MS lesions are tissue damages, such as inflammation or scars, visible in MRI scans, aiding in early diagnosis and therapy decisions.
- [Lesions in MRI Images](#): T2 lesions appear bright, indicating inflammation or tissue destruction; T1 lesions appear dark, showing tissue damage; Gadolinium-enhanced lesions highlight new inflammation during acute MS episodes.
- [McDonald Criteria](#): Neurologists use McDonald criteria, incorporating MRI findings, for early MS diagnosis and treatment initiation.
- [Regular Monitoring Examinations](#): MRI is vital for tracking disease progression and adjusting therapies based on new or enlarged lesions.
- [A Tip for You](#): Patients are encouraged to review their MRI scans with their doctor to better understand their condition and disease progression.
