The tool for neurosurgeons, neuroradiologists, and neuro-oncologists. Load any DICOM series — MRI or CT — and segment tumors, hemorrhages, and metastases in minutes. Live volumes, ABC/2 estimates, and publication-ready PDF reports.
Free beta · No account required · macOS 12+
Designed for clinical and research use
From raw DICOM to signed PDF report in under 5 minutes — without leaving your desk.
Click on a lesion and BrainVol automatically selects the region based on local intensity. Adapts to both CT Hounsfield Units and MRI signal — no manual threshold tuning needed.
CT + MRITrue voxel-by-voxel volume calculation with partial-volume error estimation. Simultaneous CE and nCE (FLAIR) compartment volumes. ABC/2 comparison for hemorrhage cases.
High accuracyOne-click 3D surface rendering of any segmented lesion. Rotate, inspect, and include in reports or presentations.
InteractiveOpen coronal and sagittal reconstructions on the fly. Paint and edit the mask directly in any plane, with synchronized window/level matching the axial view.
Axial · Coronal · SagittalAutomatic Extent of Resection classification per RANO criteria — gross total, near total, subtotal, or partial resection — computed from CE and FLAIR volumes the moment you segment. Built-in surgical trial reference (MISTIE III, ENRICH, STICH II) for hemorrhage cases.
Gliomas · ICHExport a professional, print-ready report with axial slice image, volume measurements, patient data, and RANO EOR classification for gliomas. One click.
One clickSave segmentation plans per patient and compare volumes across time points. Growth percentage with visual trend indicators — ideal for tumor response assessment.
LongitudinalDrag and drop any DICOM folder — no conversion needed. Supports MRI (T1+Gd, FLAIR, T2, DWI) and CT. Auto-detects series type and suggests the right layer.
Any scannerExport segmentation masks as RT-STRUCT or Secondary Capture DICOM overlays — compatible with PACS, radiotherapy planning, and research pipelines.
RT-STRUCT · SCEvery segmentation can be reviewed and retouched in all three planes simultaneously — with Brush, Magic Wand, and Eraser. What you paint in one plane is instantly visible in the other two. No switching apps, no importing masks.
One click generates a signed PDF with the MRI image, segmentation volumes, RANO Extent of Resection classification, and all study metadata — ready to print or share.
Specialized workflows, labels, and clinical criteria for each pathology.
Drag a folder or use the open dialog. BrainVol scans all series automatically, detects the modality, and suggests the right sequence to load.
Choose from gliomas, metastases, meningiomas, schwannomas, intracerebral hemorrhages, subdural hematomas, or other. BrainVol configures the right tools and clinical criteria automatically.
Click on the lesion with the Magic Wand for automatic region growing, or paint manually with the Brush. Refine with the Eraser. Volume updates live as you paint.
Hit Calculate Volumes for a detailed breakdown — surgical thresholds, RANO EOR, or per-lesion rankings. Export a PDF report in one click.
Watch a real segmentation from DICOM load to PDF report in under 3 minutes.
