How DN Viewer compares on Windows

If you've been using RadiAnt, MicroDicom, or a browser-based viewer, here's how DN Viewer fits in.

  • vs RadiAnt DICOM Viewer: RadiAnt is a capable Windows-only viewer but requires a paid licence for continued use after the trial. DN Viewer is free for core features, includes built-in DICOM server access and AI-assisted reporting, and is available on both Windows and Mac.
  • vs MicroDicom: MicroDicom is a free Windows DICOM viewer focused on basic viewing. DN Viewer adds near-instant MPR, 3D rendering, AI-powered segmentation, and built-in AI-assisted reporting — in a single native desktop app.
  • vs browser-based viewers: Web DICOM viewers depend on your internet connection and browser performance. DN Viewer runs natively on Windows, so MPR and 3D rendering use the GPU directly — no browser overhead, no lost tabs.
