A browser-based alternative to desktop DICOM viewers

If you searched for a RadiAnt DICOM Viewer download, MicroDicom viewer, Weasis DICOM viewer, Horos for Mac, IMAIOS or Sante DICOM Viewer, MyResultLab gives you a lightweight online option for quick local viewing. Dedicated desktop viewers are still better for PACS, regulated diagnostic reading, printing workflows and advanced clinical reporting.
