Treatment Monitoring in Multiple Sclerosis - Efficacy and Safety

Area of Science:

• Neuroimaging
• Neurology
• Radiology

Background:

• Multiple sclerosis (MS) is a central nervous system inflammatory disease.
• Detecting inflammatory activity is crucial for MS management.
• Magnetic resonance imaging (MRI) is the gold standard for visualizing MS-related brain inflammation.

Purpose of the Study:

• To review the role of MRI in detecting and monitoring inflammatory activity in MS.
• To discuss established and emerging MRI markers for MS.
• To highlight the utility of MRI in assessing treatment complications.

Main Methods:

• Review of current literature on MRI techniques in multiple sclerosis.
• Analysis of established MRI markers (contrast-enhancing lesions, active T2 lesions).
• Exploration of novel MRI markers (slowly expanding lesions, phase rim lesions) and advanced techniques (volumetric, quantitative MRI).

Main Results:

• Established MRI markers effectively detect active inflammation in MS.
• Emerging markers show promise for monitoring chronic inflammation but need validation.
• Advanced MRI techniques are primarily used in clinical trials.
• MRI is essential for pharmacovigilance, particularly with treatments like natalizumab.

Conclusions:

• MRI is indispensable for diagnosing and monitoring MS inflammatory activity.
• Continued research into novel MRI markers and techniques will enhance MS patient care.
• MRI plays a critical role in ensuring patient safety during disease-modifying therapy.
