[Magnetic Resonance Imaging of Multiple Sclerosis]

Area of Science:

• Neurology
• Radiology
• Medical Imaging

Background:

• Multiple sclerosis (MS) diagnosis and management heavily rely on Magnetic Resonance Imaging (MRI).
• MRI is integral to established diagnostic criteria and differential diagnosis in suspected MS cases.
• The accuracy of MRI interpretation can significantly reduce misdiagnosis rates, estimated up to 10%.

Purpose of the Study:

• To review the multifaceted utility of MRI in the diagnosis and treatment of multiple sclerosis.
• To highlight MRI's role in establishing diagnostic criteria and differential diagnosis.
• To discuss MRI's application in monitoring disease-modifying therapies (DMDs) and detecting treatment-related adverse events.

Main Methods:

• Review of current literature on MRI applications in multiple sclerosis.
• Analysis of MRI's role in diagnostic criteria (e.g., McDonald criteria).
• Examination of quantified MRI data in clinical trials and patient monitoring for DMDs.

Main Results:

• MRI is essential for MS diagnosis, aiding in differential diagnosis and reducing misdiagnosis.
• Quantified MRI data serve as key outcomes in clinical trials for DMDs.
• MRI effectively monitors DMD efficacy and facilitates early detection of side effects, such as progressive multifocal leukoencephalopathy (PML).

Conclusions:

• MRI is indispensable for the diagnosis, biomarker assessment, and safety monitoring of patients with multiple sclerosis.
• The application of MRI extends to individual patient treatment monitoring, including efficacy and adverse event detection.
• Continued advancements in MRI technology promise further improvements in multiple sclerosis care.
