Using MRI to make informed clinical decisions in multiple sclerosis care

Area of Science:

• Neurology
• Radiology
• Immunology

Background:

• Multiple sclerosis (MS) treatment offers numerous anti-inflammatory, disease-modifying therapies.
• Predicting individual patient response to specific MS therapies remains challenging.
• Magnetic Resonance Imaging (MRI) is crucial for selecting and monitoring MS treatments.

Purpose of the Study:

• To review the role of MRI in guiding therapeutic decisions for multiple sclerosis.
• To highlight the significance of subclinical disease activity detected by MRI.
• To establish criteria for changing MS therapy based on MRI findings.

Main Methods:

• Review of current literature on MRI in multiple sclerosis management.
• Analysis of the prognostic implications of lesion burden on MRI.
• Evaluation of clinical stability versus MRI-detected disease activity.

Main Results:

• The number of lesions at baseline and the appearance of new lesions during therapy impact long-term prognosis in MS.
• Accumulating lesions on MRI may necessitate a change in therapy for optimal outcomes.
• For patients with stable disease, MRI frequency can potentially be reduced.

Conclusions:

• Brain MRI scans are essential adjuncts to clinical evaluations for detecting subclinical MS disease activity.
• Therapy modification in MS may be warranted based on MRI findings alone, even in clinically stable patients.
• The presence of 2-5 T2-weighted lesions or 1-2 gadolinium-enhancing lesions on MRI signals a threshold for concern, prompting consideration of treatment change.
