What feature would you use if you wish to recall a previous exam from the PACS system to your ultrasound machine?

• A. Storage commitment
• B. Query/retrieve
• C. DICOM store
• D. Worklist

Answer: (B)

The feature you would use to recall a prior exam from the PACS to your ultrasound machine is the Query/Retrieve function. The ultrasound system acts as a DICOM client and can search the PACS for a previous study using patient identifiers, then request the study transfer back to the modality so you can view it. This is typically done with C-FIND to locate the study and C-MOVE or C-GET to pull the images onto the machine. Storage commitment focuses on confirming that the stored data has been safely written to the archive, not on pulling it back to the modality. DICOM store is the operation of sending images to the PACS, not retrieving from it. Worklist provides a list of planned or scheduled studies for imaging, not a method for recalling existing studies.
