Scans we cover
X-ray, CT, MRI and mammogram, in one place.
Each kind of scan has a viewer and open research models trained on public data. Pick one to see what the models do and how they scored.
-
X-ray · chest X-ray · wrist X-ray · spine X-ray
What the viewer shows
Single pictures and series: zoom and brightness. Chest, wrist and spine pictures are shown here.
Research models
-
CT · organs CT · lungs CT
What the viewer shows
Scroll through the slices, change the brightness window and zoom. The 3D sample shows the organs and bones as coloured shapes.
Research models
-
MRI · spine MRI
What the viewer shows
Scroll through the slices of a spine MRI, with zoom and brightness. Discs and vertebrae can be coloured by name.
Research models
-
Mammogram Mammogram
What the viewer shows
Opens the picture for zoom and brightness, like any other X-ray style picture.

Research results
One result from each research model.
Each row is one result: the dot is the score and the line is its 95% interval, the range the score would most likely fall in on new data.
A filled dot is a held-out test, data the model never saw while training. A hollow dot is development data.
Research results on public test data. They say nothing about your own scan.
Show the numbers
| Result | Metric | Score | 95% interval | Test set | Kind |
|---|---|---|---|---|---|
| Chest X-ray research model: Agreement with ChestX-ray14's labels, mean over its 14 label types | AUROC | 0.818 | 0.811 to 0.823 | NIH's official test list: 25,596 pictures of 2,797 patients | held-out test |
| CT organ outliner: Mean over 115 structures | Dice | 0.867 | 0.854 to 0.878 | Held-out test: 89 CT scans | held-out test |
| Disc grading research model (MRI): Agreement with SPIDER's Pfirrmann grades, held-out test | kappa | 0.773 | 0.664 to 0.853 | SPIDER held-out test: 44 patients, 264 discs, opened once | held-out test |
| Fracture research model (X-ray): Agreement with GRAZPEDWRI-DX's fracture labels, children's wrists | AUROC | 0.979 | 0.974 to 0.984 | GRAZPEDWRI-DX held-out test: 4,067 pictures of 1,176 patients with a certain label | held-out test |
| Lung nodule research model (CT): Share of LUNA16's marked nodules matched, averaged over seven false-alarm allowances | percent | 88.0 | 86.0 to 89.6 | LUNA16: 888 thin-slice LIDC-IDRI scans, five folds, each read by a model that never trained on it | development |
| Mammogram research model: Agreement with CMMD's benign/malignant labels, per picture | AUROC | 0.793 | 0.774 to 0.811 | CMMD: 3,744 pictures of 1,775 patients, five folds split by patient | development |
| Lumbar spine X-ray corner reader: Share of BUU-LSPINE's marked vertebrae matched, side view (IoU 0.5) | percent | 97.9 | 97.3 to 98.4 | All 2,000 BUU-LSPINE patients, out of fold | development |
Where the models fall short
- CT organ outliner. Both kidney cysts score 0.0000 on the test scans. Vertebra C6, the gallbladder, the portal and splenic veins and the adrenal glands are the next weakest.
- Disc grading research model (MRI). The three current versions have not been scored on held-out test patients; their results are development results.
- Lung nodule research model (CT). All the nodule-finding numbers are development scores from the same 888 scans used to choose between designs; there is no untouched test.
- Mammogram research model. Where no lesion outline exists the score is close to a coin toss: version 38 scores 0.5726 on those 1,002 pictures.
What the viewer does, and what it does not.
