Magnetic resonance imaging in multiple sclerosis: diagnostic value and clinical correlations

Area of Science:

• Neurology
• Radiology
• Immunology

Background:

• Multiple Sclerosis (MS) diagnosis relies on clinical evaluation and paraclinical markers.
• Cerebrospinal fluid (CSF) findings and auditory brainstem responses (ABR) are established diagnostic tools.
• Magnetic Resonance Imaging (MRI) offers detailed visualization of the central nervous system.

Purpose of the Study:

• To evaluate the diagnostic sensitivity of MRI in multiple sclerosis (MS).
• To compare MRI sensitivity with CSF findings and ABR.
• To correlate MRI lesion severity with clinical data and CSF immunoglobulin abnormalities.

Main Methods:

• Investigated 101 patients with suspected, possible, probable, and definite MS using McDonald and Halliday criteria.
• Utilized MRI, CSF analysis for oligoclonal banding, and ABR.
• Assessed correlations between MRI findings, clinical disability, disease duration, progression rate, and CSF immunoglobulin levels.

Main Results:

• MRI detected demyelinating lesions in 96% of definite MS cases, outperforming CSF and ABR in some categories.
• MRI findings correlated with patient disability and disease duration.
• CSF oligoclonal bands and elevated IgG index were associated with more extensive white matter lesions on MRI.

Conclusions:

• MRI is a highly sensitive tool for diagnosing multiple sclerosis (MS).
• MRI provides valuable correlations with clinical disease severity and progression.
• Combining MRI with CSF analysis enhances the understanding of MS pathophysiology and extent.
