What PACS CQI activity documents images that are of poor quality?

• A. Recognition of nondiagnostic images
• B. Repair of corrupted files
• C. Automatic histogram equalization
• D. Archival of high-resolution copies

Answer: (A)

In PACS CQI, the important practice is recognizing when an image cannot be interpreted due to quality issues and documenting that status for quality improvement. This involves flagging nondiagnostic images so the team can track how often they occur and investigate causes like equipment problems, patient motion, or protocol errors. Logging these cases creates data for root-cause analysis, training, and process changes to reduce repeats and improve patient care.

The other options don’t fit this documenting-and-tracking role. Repairing corrupted files is a remediation action taken after a problem is found, not the documentation of a quality issue. Automatic histogram equalization is a processing technique that can enhance image appearance, not a record of poor-quality images. Archiving high-resolution copies concerns storage and preservation rather than identifying and documenting images that are nondiagnostic.
