Stroke Bricks - spatial brain regions to assess ischaemic stroke localisation.

Area of Science:

• Neurology
• Radiology
• Medical Imaging Analysis

Background:

• Computer-aided analysis of non-contrast computed tomography (NCCT) aids ischemic stroke diagnosis by visualizing lesions.
• Current methods may overinterpret ischemic areas, necessitating improved accuracy in radiological assessment.

Purpose of the Study:

• To introduce Stroke Bricks (StBr), a novel spatial division method for brain tissue analysis in ischemic stroke.
• To correlate neurological deficits with specific brain regions to enhance diagnostic accuracy.

Main Methods:

• Stroke Bricks (StBr) divide brain tissue into regions linked to specific clinical symptoms of ischemic stroke.
• Formalized mapping translates neurological stroke deficits into potential ischemic lesion areas.
• StBr are attributed to defined areas of impaired blood supply based on symptom mapping.

Main Results:

• The StBr concept facilitates integrated radiological CT-based assessment of suspected stroke.
• It optimizes computer-aided tools for evaluating stroke site and extent.
• Case studies demonstrated the practical utility of the StBr approach.

Conclusions:

• Stroke Bricks (StBr) provide a structured approach to ischemic stroke assessment using NCCT.
• This method aids in diagnosis, therapeutic outcome prediction, and patient selection for reperfusion therapy.
• StBr integration into clinical practice can improve the precision of stroke evaluation.
