MACOS GUIDE · PATIENT MEDICAL SCANS
Received a hospital CD or USB with your CT, MRI or X-rays and can’t open it on your Mac? You’re not alone. Most hospital discs come with old Windows-only software (.exe) that doesn’t work on macOS.
Here’s the fastest way to open your medical scans on a Mac — completely free and private.
All processing happens locally in your browser · Your medical images never leave your Mac
Hospital imaging departments usually burn a Windows viewer onto the disc. That viewer:
The actual medical images are stored as DICOM files (.dcm) or inside a folder structure with a DICOMDIR index. You don’t need the hospital software to view them.
