The acronym PACS stands for which term?

• A. Picture Archiving and Communication System
• B. Patient Access and Clinical System
• C. Protocol for Archival and Communication Storage
• D. Primary Archive and Control System

Answer: (A)

PACS is the digital workflow that handles medical images: acquisition from imaging devices, storage in a secure archive, and sharing or viewing across the hospital. The term stands for Picture Archiving and Communication System, which fits the three main ideas: Picture (the images themselves), Archiving (storing them for retrieval), and Communication (moving and accessing images between devices and clinicians). The other options don’t reflect the established term used in radiology informatics: they describe access, protocols, or generic archiving ideas rather than the specific system for image storage and exchange. PACS also typically uses standards like DICOM to ensure images and related data can be exchanged smoothly across different devices and software.
