OsiriX Lite
OsiriX Lite is a macOS DICOM viewer for opening, reviewing, and post-processing medical imaging studies in radiology workflows.
What is OsiriX Lite?
OsiriX Lite is a native Mac medical imaging viewer for working with DICOM studies. It helps radiologists, clinicians, researchers, and imaging students open and review scans such as CT, MR, PET, and other medical image series on macOS. The app includes tools for image viewing, measurement, and 2D and 3D post-processing, making it useful for teaching, case review, and non-diagnostic evaluation workflows. OsiriX Lite is the limited free edition of the OsiriX product line from Antoine Rosset, while the full OsiriX MD edition adds certified medical-use capabilities and fewer restrictions. Users commonly encounter it in hospital, clinic, imaging lab, and academic environments where DICOM compatibility and Mac-based image review are important.

Safety overview
Status: Mostly safe
OsiriX Lite is legitimate medical imaging software for Mac. It normally needs access to local image files and may handle sensitive health information inside imported studies, so standard privacy precautions matter when using shared computers or non-production data. The Lite edition is intended as a limited free version rather than a full clinical deployment tool, and users should avoid relying on it for regulated diagnostic use where certified workflows are required. Keep patient data protected, import only trusted imaging files, and follow your organization's imaging and privacy policies.
Recommendation: Keep OsiriX Lite if you use your Mac to review DICOM studies, learn imaging workflows, or test OsiriX features. If you no longer open medical image files with it, you can remove it to free space, but do so only after confirming you do not need any saved studies, local database content, or related settings.
