What is the primary purpose of picture archiving and communication system (PACS) in radiology?

  1. To archive patient records

  2. To facilitate communication between departments

  3. To store, retrieve, and distribute radiology images

  4. To manage patient billing

The correct answer is: To store, retrieve, and distribute radiology images

The primary purpose of a Picture Archiving and Communication System (PACS) in radiology is to store, retrieve, and distribute radiology images efficiently. PACS allows healthcare providers to access images digitally, which enhances workflow, facilitates quicker decision-making, and improves patient care by providing easier access to diagnostic imaging tests. Therefore, option C is the correct answer as it aligns with the core function of PACS in radiology. Options A, B, and D are not the primary purposes of PACS. While archiving patient records, facilitating communication between departments, and managing patient billing are important functions within healthcare settings, these are not the main focus of why PACS is specifically implemented in radiology.
