Diagnostic Accuracy of the Relative Subcortical Atrophy Index in Idiopathic Normal Pressure Hydrocephalus

Key Points

• The aim is to assess how accurately the RSCA index diagnoses idiopathic normal pressure hydrocephalus (iNPH).
• Evaluated the diagnostic accuracy of the RSCA index for iNPH.
• Analyzed postoperative changes related to the RSCA index.
• Used radiological assessments for diagnosis and follow-up.
• The RSCA index showed high diagnostic accuracy for iNPH.
• Significant variations in the RSCA index were observed post-surgery.
• Supports the index's potential as a reliable biomarker for both diagnosis and surgical follow-up.
