Understanding PACS: The Digital Backbone of Medical Imaging

By December 29, 2025

PACS, or Picture Archiving and Communications System, represents the modern digital infrastructure that revolutionizes how radiology images are stored, accessed, and shared within healthcare. This system enables clinicians and radiology professionals to manage imaging data electronically, replacing traditional film-based methods with efficient, secure, and easily retrievable digital archives.

The PACS platform is accessible not only by radiology specialists but also by a broad range of healthcare professionals outside the Radiology department. To interpret X-rays and other imaging results, individuals must be qualified medical practitioners or possess advanced clinical training. When a patient undergoes a radiological examination, the resulting images are uploaded directly into the PACS. A designated radiologist or reporting radiographer then reviews these images, generating a diagnostic report that is sent back to the referring clinician. This process ensures timely and accurate communication, facilitating appropriate treatment plans.

Since the system operates on a national level within Scotland, it offers seamless access to imaging data across different regions. Whether a patient relocates or is referred to a different health board, their previous imaging results remain accessible, eliminating the need for repeated scans and reducing unnecessary exposure and costs. Additionally, the Image Exchange Portal (IEP) enhances cross-border sharing by securely transmitting imaging data to specialized healthcare facilities across the UK, such as if a patient requires treatment at Great Ormond Street Hospital or moves to England. For more insights into how immersive technologies are transforming patient care, you can explore VR and AR applications in healthcare.

Referral Routes

Access to the PACS system is primarily granted to radiology staff and other clinicians with specialized training outside of Radiology. Only qualified medical professionals authorized to interpret imaging results can view and act upon the scans, ensuring patient safety and diagnostic accuracy.

Location and Opening Hours

The PACS service supports healthcare facilities across Fife, with dedicated teams based at Queen Margaret Hospital in Dunfermline and Victoria Hospital in Kirkcaldy. The PACS system itself operates continuously, 24 hours a day, every day of the week, providing round-the-clock availability for urgent and routine imaging needs.

The PACS team offers support from Monday through Friday, between 09:00 and 17:00. For any inquiries or assistance, contact them via email at fife.pacsteam@nhs.scot.
