How to View a DICOM CD From Your Hospital
Hospitals and imaging centers often hand you your MRI, CT or X-ray study on a CD or DVD. The disc usually includes a Windows-only viewer that may not run on your computer at all. Here is how to see your images in minutes, on any system, without installing anything.
Step by step
- Insert the disc and open it in your file explorer. No disc drive? Copy the contents to a USB stick on a computer that has one — the files are ordinary data files.
- Find the image folder. Look for a folder called
DICOM,IMAGES,PAT_0000or similar. You will often see aDICOMDIRfile next to it — that's the study index. The image files inside frequently have no extension; that's normal. - Open the free online DICOM viewer in your browser (Windows, Mac and Linux all work).
- Drag the whole folder onto the viewer. Every series on the disc appears in the left sidebar with thumbnails — click one to review it, scroll through slices with your mouse wheel, and adjust brightness/contrast by dragging with the middle mouse button.

The files never leave your computer — nothing is uploaded to any server.
Open Your CD's ImagesTroubleshooting
- "The CD has an .exe viewer that won't start." Those bundled viewers are usually old and Windows-only. Ignore the program — the DICOM folder is what matters, and any DICOM viewer can open it.
- "The files have no extension." They are still DICOM files. Drag the folder in as-is; the viewer detects the content, not the file name.
- "I only see reports, not images." Some discs contain PDF or
structured reports alongside images; check every subfolder under
DICOM. - "The study is huge." Large multi-series studies can take a moment to parse — the sidebar fills in as files are read.
A note on privacy
Your disc contains identifiable medical data. A browser-based viewer that processes files locally — like this one — means your study is never uploaded, stored or indexed by a server. If you need a doctor to review the study, hand over the disc or the original DICOM files rather than screenshots.
