Comprehensive MR Stroke Evaluation
DWI-ASPECTS regional summary, FLAIR signal intensity ratio, and perfusion-diffusion volumetric comparison from DSC MRI — quantitative measurements presented for interpretation by qualified healthcare professionals.
Processing Pipeline
Fully automated from DICOM ingest to clinical report.
Pipeline
- 1Auto-segregate Perfusion, DWI and FLAIR series from mixed upload
- 2Brain extraction and motion correction
- 3Arterial and venous reference detection
- 4Perfusion map computation (CBF, CBV, MTT, Tmax)
- 5Automated DWI region segmentation and volume
- 6DWI-ASPECTS regional summary across 10 MCA territory regions
- 7FLAIR signal intensity ratio (SIR) computation
- 8Perfusion-diffusion volumetric comparison
Analysis Outputs
- CBF, CBV, MTT, Tmax maps
- DWI region segmentation
