BrainDS + PET · Signal
PET signal, measured on the patient’s own anatomy.
BrainDS + PET is an optional BrainDS module. It aligns brain PET to the same patient’s T1-weighted MRI, measures uptake region by region as SUVR, and compares it with reference data for each tracer — so structure and signal are reviewed together.
Optional module · Research use only: Available now for research use only. Not yet approved as a medical device by MFDS (KFDA), the FDA or CE — not for clinical or diagnostic use.

01 / Rationale
Why pair PET with MRI?
Structural MRI and PET answer different questions. Measuring both on one segmentation ties every PET value to a named region of the same brain.
MRI · Structure
How much tissue is there
Structural MRI measures the size and shape of brain regions — the basis of BrainDS volumetry.
PET · Signal
What the tissue is doing
PET images a radiotracer, showing processes such as glucose metabolism or protein deposition that may change before structural loss is visible.
BrainDS + PET
Both, on one map
PET is sampled inside the regions of the patient’s own BrainDS segmentation, so structure and signal can be read region by region.
02 / Workflow
From paired scans to a PET report
PET analysis reuses the BrainDS segmentation of the same patient.
01
Pair
Select a brain PET study and a matching 3D T1-weighted MRI of the same patient. The tracer is recognised from the DICOM metadata.
02
Segment
BrainDS segments the T1 scan into its 95 regions — the same map used for structural analysis.1
03
Align
The PET volume is registered to the patient’s own T1 scan, and a check image confirms the alignment.
04
Quantify
Regional and composite SUVR are calculated with the cerebellar cortex as the reference region, then compared with reference data for the tracer as Z-scores, percentiles and percentage differences.
05
Report
An eight-page PET report in English or Korean, with fused PET–MRI views and longitudinal trends when earlier PET studies exist.
03 / Tracers
Tracer-aware quantification
Each tracer gets its own summary measures and its own reference data.
Amyloid
FlorbetapirAmyloid deposition
- Global cortical SUVR
- Z-score and % difference versus reference data
- Left and right regional SUVR tables
Tau
FlortaucipirTau deposition
- Composite SUVR for Braak regions I–II, III–IV and V–VI
- Z-score and % difference versus reference data
- Left and right regional SUVR tables
Tracer support is confirmed for each research project.
04 / Capabilities
Review signal and structure together
The same study list, viewer and report format as BrainDS.
Regional summary at a glance
Each study is summarised by region — SUVR, Z-score and percentage difference — beside colour-mapped cortical views, with full left–right tables behind it.
- SUVR, Z-score and % difference by region
- Colour-mapped cortical views
- Regional tables with reference ranges
Follow PET over time
When earlier PET studies exist, BrainDS + PET charts regional SUVR or percentile across visits against the reference band.
- Longitudinal SUVR and percentile charts
- Same regions as the structural trends
- CSV and PNG export
Fused PET–MRI viewer
Review PET over the patient’s MRI in three planes. Adjust PET and segmentation opacity, brightness and contrast, or switch to contours only.
- PET overlaid on T1 MRI in three planes
- Independent PET and segmentation opacity
- Region visibility by lobe
One installation
PET runs inside the same on-premise BrainDS installation — no separate platform to deploy, secure or learn.
- Shared study list and viewer
- Same report format and languages
- Images stay inside your network
05 / Report
Inside the PET report
Sample pages from the eight-page PET report: tracer summaries, regional PET intensity maps with SUVR tables, and a plain-language region guide.
Sample pages from public research data (ADNI). Identifiers are removed and automated interpretation text is blurred.

08 / FAQ
FAQ
Which PET tracers are supported?
BrainDS + PET recognises FDG, amyloid (florbetapir) and tau (flortaucipir) PET from the DICOM metadata. Tracer support is confirmed for each research project.
Why is a T1-weighted MRI required?
PET is aligned to the patient’s own T1 scan so that uptake is measured inside regions defined by the BrainDS segmentation of that same brain.
Which reference region is used for SUVR?
The cerebellar cortex of both hemispheres.
Is BrainDS + PET a separate product?
No. It is an optional module that runs inside a BrainDS installation and shares its study list, viewer and report format.
Is it approved for clinical use?
No. BrainDS + PET is available for research use only. It has not yet been approved as a medical device by MFDS (KFDA), the FDA or CE.
