What is the primary purpose of a PACS?

• A. To replace radiologists
• B. To store, retrieve, distribute, and view medical images
• C. To generate reports
• D. To compress all data

Answer: (B)

PACS is a digital system for managing medical imaging. Its primary purpose is to store, retrieve, distribute, and view medical images across the care team. Imaging studies from different modalities are kept in a centralized archive, making it quick to pull up a study, view it on workstations, and share it with radiologists or clinicians at different locations. This improves workflow, speeds consultations, and allows easy comparison with prior images. It supports the radiologist by providing fast access to images, but it does not replace the radiologist. Generating reports relies on reporting workflows that accompany imaging systems, not the PACS itself. While some data compression can be used to save space, the main goal is efficient storage and access to imaging data.
