Questions & answers

What does RADAR do?

RADAR scores contrast-enhanced abdominal CT scans across 18 structures and up to 146 findings. You get per-finding scores — top-10 bars plus a searchable, sortable table — not generated report text or a confirmed diagnosis.

What files can I upload?

Either one volume file (.nii, .nii.gz, .nrrd, .mha) or one full DICOM series (multiple .dcm or extensionless files, or a .zip — nested folders are OK; the series with the most slices is scored). A single .dcm is one slice, not a volume. Header/raw pairs (.mhd, .nhdr, .hdr, .img, .raw) must be converted to a supported volume first. A DICOM series needs at least 8 slices.

How big can files be, and how long does scoring take?

Browser limit is 500 MB per file; on the public demo the free edge refuses bodies over about 100 MB, so the site pre-checks remote totals at about 95 MB. Scoring usually takes about a minute (around 90 seconds), one case at a time — if the queue is full you get a queue-full error and should retry.

Is this a medical diagnosis?

No. Research assistance only (CC BY-NC-SA 4.0). Scores must not substitute for clinical review.

Is my scan private? Do you keep my data?

Only upload scans you are allowed to share — ideally fully anonymized, with no patient name, ID, or dates. Your files are used only to compute scores and are deleted afterwards: not kept, reused, or shared. The public demo has no accounts and is open to everyone, so never submit anything identifiable or protected.

Can I trust the scores?

Treat them as a second opinion for research, not a diagnosis. This is a free demo of the published RADAR model (see the model link below) for non-commercial research — it only reads contrast-enhanced abdominal CT, it can be wrong, and it never replaces an expert's review. If a case fails, it is usually the file: one full series, anonymized, under the size limit (see above) — fix that and try again.
