PACS primarily provides which function in medical imaging workflows?

• A. Image acquisition control
• B. Archived storage and retrieval of images
• C. Image compression
• D. Patient scheduling

Answer: (B)

PACS primarily provides centralized storage and rapid retrieval of medical images across the clinical network. It serves as a centralized archive for DICOM images and related patient data, enabling storage, long‑term preservation, and easy access to images from multiple modalities and workstations. In day‑to‑day use, imaging data are sent from the modality to the PACS where they’re stored and indexed, and clinicians—often radiologists—retrieve and view both current and prior studies across departments or sites, which speeds diagnosis and improves continuity of care. While some PACS systems include image compression to save storage and bandwidth, that is a supporting feature rather than the main purpose. Acquisition control and patient scheduling are managed by other systems: imaging devices handle capture, and scheduling/tracking is handled by RIS/HIS.
