What does PACS stand for?

• A. Picture archiving and communication system
• B. Personal access and coordination system
• C. Professional archiving and care system
• D. Public access and control system

Answer: (A)

The idea being tested is what PACS stands for in medical imaging and what that system does. PACS is Picture Archiving and Communication System. It’s the networked setup that stores digital medical images (like X-ray, CT, MRI, ultrasound) in a centralized archive and makes them available for viewing and sharing across clinicians and departments. The “archiving” part refers to storing the images, while the “communication” part refers to transferring and displaying them where needed, often across the hospital and beyond, using standards like DICOM. This combination is what makes PACS essential for efficient imaging workflows.

Other options don’t fit the established terminology: they don’t describe the storage and rapid, wide sharing of radiology images within a healthcare setting.
