Most medical images require a special viewer. Typically, the doctor's office will include the viewer on the CD/DVD that they give you with the image(s).
Put the disk in your CD/DVD drive on your computer. If it doesn't automatically start to play, click Start, then click "Computer," and double-click the icon for your CD/DVD drive.
You'll have to look through the list of files for something that looks like a viewer. You should be able to determine this from the name. Double-click to start the viewer application.
If you can't figure it out, get to the point where you have the contents of the disk shown in Windows Explorer (the file manager, not the Internet browser), take a screenshot and include it in your reply here.
