TL;DR
RadiAnt DICOM Viewer (Medixant, Poland) is desktop software for Windows 7–11, sold after a free trial as a time-based or permanent license, with MPR, 3D volume rendering and PET-CT fusion; it has no native Mac version, and its terms say it is not certified as a medical product. RadDream (5C Network, India) is a browser-based viewer with nothing to install and the reading room inside 5C's platform, with Bionic AI findings on the image and the report editor one click away.

Should you install a viewer or open one in the browser?
RadiAnt is built for one desk. A radiologist created it after watching colleagues struggle with slow patient-CD viewers, per Medixant, and it shows: install it on a Windows PC and you get MPR, 3D, PET-CT fusion and a local archive for studies from CDs, USB drives and PACS. For one doctor at one workstation, especially offline, that is a strong setup.
A desktop viewer stays on its desktop. The studies live on that PC, there is no native Mac version, AI and reporting come from somewhere else, and RadiAnt's own terms say it is not certified as a medical product and should not be used to interpret and report studies.
RadDream is built for a reading room. It opens in a browser on any computer, Bionic AI has pre-read the study, its findings sit on the image, the draft impression is beside it and the report editor is one click away. For the archive side, see 5C SuperPACS and our guide to the best PACS software in India. Comparing web viewers? Read RadDream vs MedDream and RadDream vs OHIF.
