Clinical Scorecard: Association Between Parasagittal Dura Volume and Systemic Inflammation Blood Markers

At a Glance

Key Highlights

• PSD volume shows marked inter-individual variability and associates with CSF tracer clearance efficiency.
• Systemic inflammation markers (CRP, Hb, EVF, PLT, Neu, Lymph, NLR, PLR) were studied for correlation with PSD volume and clearance function.
• AI-assisted segmentation combined with manual review was used for accurate PSD volume measurement on FLAIR MRI sequences.

Guideline-Based Recommendations

Diagnosis

• Use intrathecal contrast-enhanced MRI with FLAIR sequences to segment and measure PSD volume.
• Assess systemic inflammation using blood markers including CRP, hemoglobin, erythrocyte volume fraction, platelet count, neutrophils, lymphocytes, NLR, and PLR.

Management

• Consider the role of systemic inflammation in modifying meningeal clearance function in neurological diseases.
• Monitor PSD volume changes as a potential biomarker for impaired meningeal clearance in neurodegenerative conditions.

Monitoring & Follow-up

• Perform serial MRI and blood marker assessments to evaluate PSD volume and systemic inflammation status.
• Evaluate CSF tracer enrichment in PSD at multiple time points post-intrathecal injection to assess clearance function.

Risks

• Contrast allergy contraindicates intrathecal contrast-enhanced MRI.
• Potential confounding factors include age and chronic inflammatory conditions affecting blood markers.

Patient & Prescribing Data

Adults undergoing diagnostic intrathecal contrast-enhanced MRI for neurological evaluation

No direct treatment prescribed; data supports understanding of systemic inflammation impact on meningeal clearance and potential implications for neurodegenerative disease management.

Clinical Best Practices

• Combine manual and AI-assisted segmentation for efficient and accurate PSD volume measurement.
• Collect blood samples in the morning concurrent with MRI to standardize inflammation marker assessment.
• Interpret PSD volume and blood inflammation markers in the context of patient clinical status and neurodegenerative disease risk.
