Free online PET scan viewer
Open a PET or PET-CT study and explore it in 2D and 3D right in your browser. The files are decoded locally — nothing is uploaded — so your images stay private on your device. Axial, coronal and sagittal views are MPR reformats rebuilt from the volume, and a slab MIP or MinIP is one click away.

FAQ
- Is this PET viewer free?
- Yes. Viewing PET and PET-CT images here is completely free and needs no account.
- Are my PET images uploaded to a server?
- No. The DICOM/NIfTI files are decoded locally in your browser, so the pixel data never leaves your device.
- Can it explain my PET scan?
- The viewer is free. For a plain-language explanation you can create an account and run an AI report on your uploaded, de-identified scan.
- Does it support MPR and MIP?
- Yes. The viewer reads the whole volume rather than a stack of pictures, so the axial, coronal and sagittal views are genuine MPR reformats. Under Advanced options you can switch on a slab projection and set its thickness in millimetres: MIP keeps the brightest voxel through the slab (areas of high uptake), MinIP the darkest (air, airways). Projections work on one plane at a time; oblique and curved (CPR) reformats are not supported yet. It is a slab MIP on the plane you are viewing, not the rotating whole-body MIP a PET workstation shows.
Want your scan explained in plain language?
The viewer is free — and so is understanding your radiologist’s report. Create an account, upload your scan (de-identified in your browser) and your report, and every finding is mapped onto the images, explained in plain language and scored — no card needed. An independent AI reading of the images is a paid extra. Informational only — not a medical diagnosis.
