DICOM images do not often have topics devoted to them online. Today I was searching for a compelling reason not to use standard DICOM file format vs compressed DICOM file format (using lossless JPEG). So I ran a few tests. I copied a DICOM image file and compressed it using Sante DICOM editor. The file size was approximately 3x smaller than the standard image size. I then compared the file headers on both files and noticed additional tag information in the compressed image header data. Comparing the image quality in Sante DICOM editor I could find no pixel difference at all.
So why would I not convert all of my DICOM images to compressed DICOM? I’m not sure yet. I suspect the only downside would be DICOM viewer issues with compressed DICOM. But who reads DICOM images with a viewer that does not support compressed DICOM? Probably no one. Prepare to be converted my standard DICOM images…
