Engineering Notes
Regulatory and clinical governance critical. DICOM images that have ever undergone lossy compression must carry '01' permanently, even if subsequently stored losslessly. Cannot be reversed.
Troubleshooting
Receiving an image with (0028,2110)='01' means irreversible information loss occurred upstream. For primary diagnostic use, verify lossy compression policy with radiologists and clinical governance.
