Unreadable CDs and Corrupted Image Files
My medical imaging CD won't open — what should I do?
Try a free DICOM viewer like RadiAnt (Windows) or Horos (Mac) and test the disc in a different computer. If it's physically scratched or truly corrupted, contact the facility's HIM department for a free replacement — they should not charge you if the original was defective.
After weeks of waiting, your imaging records finally arrive on a CD. You put it in your computer, and... nothing happens. The disc won't spin, your computer doesn't recognize it, or it shows a folder full of files that won't open. A corrupted or unreadable CD is a frustrating technical dead end.
Common Causes of Technical Failure
The problem can stem from the physical disc, the files on it, or the software used to view them.
1. Physical Disc Damage
CDs and DVDs are fragile. A single deep scratch can make a disc unreadable. The disc may have been damaged during the burning process, in transit through the mail, or by mishandling.
2. Incorrect Burning Process
The person who created the CD may have used the wrong settings or finalized the disc improperly, resulting in a disc that many computers cannot read.
3. Missing or Incompatible Viewer
You need a special viewer to open medical images. The CD should include this viewer, but sometimes it is missing. Other times, the included viewer is only compatible with Windows, leaving Mac users unable to open it.
4. Corrupted Files
The image files themselves can become corrupted during the export from the PACS or the burning to the CD. Even if the disc opens, the files may be unreadable by the DICOM viewer.
5. Lack of a CD Drive
A growing number of modern laptops, especially MacBooks, do not have a CD/DVD drive. This is not a failure of the record itself, but a common access barrier for patients.
Troubleshooting Steps
Before you contact the provider, there are a few things you can try to diagnose the problem.
Inspect the Disc
Look at the bottom surface of the CD. Do you see any significant scratches, smudges, or cracks? If the disc is visibly damaged, it is likely unusable and you'll need a replacement.
Try a Different Computer
If you have access to another computer, especially one with a different operating system (e.g., a Windows PC if you are on a Mac), try the disc there. This can help determine if the problem is with the disc or your computer.
Explore the Files Manually
If the disc opens but nothing happens automatically, explore the contents using your file browser:
- • Look for a program file named
setup.exe,viewer.exe, or similar - • Look for a folder containing DICOM files (usually with
.dcmextensions)
Download a Universal Viewer
If you can see the DICOM files but the included viewer won't run, download a free, universal DICOM viewer like RadiAnt (for Windows) or Horos (for Mac). Try to open the files using the new viewer.
Get an External CD Drive
If your computer lacks a CD drive, you can purchase an external USB CD/DVD drive for $15-$30. This is a worthwhile investment if you expect to receive more imaging CDs.
How to Request a Replacement
If you have determined that the CD is faulty, you have the right to request a replacement.
- 1.Contact the HIM Department: Call the Health Information Management department and explain the problem clearly. For example: "I received a CD of my MRI, but it is scratched and my computer cannot read it. I need a replacement copy."
- 2.Request a Different Format: If the issue is that you don't have a CD drive, ask if they can provide the records via a secure download from the patient portal instead.
- 3.Document the Failure: Keep the faulty CD as evidence. If the provider tries to charge you for the replacement, you can argue that the first copy was unusable.
Note About Fees
Providers should not charge you for a replacement if the original CD was defective. If they insist on charging, ask to speak with a supervisor and explain that you never received a usable copy of your records.
