DICOM (Digital Imaging and Communications in Medicine) and PACS (Picture Archiving and Communication System) are two essential components in modern medical imaging systems. They play distinct but interconnected roles in the management and communication of medical images. Let’s explore their differences in terms of integration, implications, and innovation:


DICOM is a standard protocol used for transmitting, storing, and sharing medical images and associated data. It defines a set of rules for formatting and exchanging images and information between various medical imaging devices and systems. DICOM ensures interoperability between different imaging modalities (such as X-ray, MRI, CT scan) and healthcare IT systems.

PACS is a comprehensive system used for archiving, retrieving, and distributing medical images within a healthcare organisation. It integrates various imaging modalities and provides a centralised database for storing and managing digital images. PACS enables healthcare professionals to access patient images and related information from different locations within the organisation.

Integration between DICOM and PACS: DICOM is the underlying protocol that facilitates communication between different imaging devices and PACS. When medical images are acquired, they are transmitted in DICOM format to the PACS for storage and management. PACS acts as a central repository that can be accessed by various departments and users, ensuring seamless integration and accessibility of images across the healthcare facility.


DICOM: The adoption of DICOM ensures standardisation in medical imaging, allowing different devices and systems to communicate effectively. It promotes interoperability, which means medical images and data can be shared between different healthcare facilities and systems, facilitating collaborative care and second opinions. DICOM also supports important image-related features, such as annotations, image processing parameters, and image compression.

PACS has a significant impact on the workflow and efficiency of medical imaging departments. It eliminates the need for physical film storage and provides immediate access to patient images. PACS streamlines the retrieval of images for diagnosis and treatment planning, leading to faster and more informed decision-making by healthcare professionals. Moreover, PACS enables remote access, allowing authorised personnel to view and interpret images from various locations, which is particularly valuable in emergency situations or when consulting specialists.


DICOM continues to evolve to keep pace with advancements in medical imaging technology. New DICOM standards and updates support emerging modalities and techniques, ensuring compatibility with the latest imaging devices and software. This constant innovation in DICOM enhances the ability to exchange and utilise complex medical imaging data effectively.

PACS has also witnessed innovation over time, incorporating features such as advanced visualisation tools, 3D image rendering, and integration with electronic health records (EHRs). Modern PACS solutions often offer web-based access, allowing healthcare professionals to review images on various devices, including smartphones and tablets. Integration with AI and machine learning algorithms is another area of innovation, empowering PACS with automated image analysis and decision support.

DICOM and PACS are integral components of medical imaging systems, with DICOM serving as the communication standard between imaging devices and PACS acting as the centralised image management system. Their integration, implications, and ongoing innovations have greatly improved medical imaging workflows, communication, and patient care in healthcare institutions worldwide.

What is veterinary PACS?

Veterinary PACS (Picture Archiving and Communication System) is a specialised version of the PACS used in veterinary medicine. Just like its human healthcare counterpart, veterinary PACS is designed to manage, store, and distribute digital medical images in the veterinary setting.

Veterinary PACS serves as a comprehensive image management solution for veterinary practices, clinics, and hospitals. It allows veterinary professionals to capture, view, store, and share various types of digital medical images, such as X-rays, ultrasounds, MRI scans, CT scans, and more. These images are acquired during the diagnosis and treatment of animals, including pets, livestock, and other animals under veterinary care.

Key features of veterinary PACS

  • Image storage and management. Veterinary PACS provides a centralised database for storing and organising digital images. This eliminates the need for physical film storage and enables easy retrieval of images for reference, diagnosis, and treatment planning.
  • DICOM support. Like human PACS, veterinary PACS utilises the DICOM standard for image exchange and communication. DICOM ensures interoperability between different imaging devices and systems, facilitating seamless data sharing.
  • Web-based access. Modern veterinary PACS solutions often offer web-based access, allowing veterinarians and authorised personnel to review images from any location with internet connectivity. This feature is especially useful for remote consultations and emergency cases.
  • Integration with veterinary information systems. Veterinary PACS may be integrated with veterinary information systems or electronic health record (EHR) systems, allowing seamless data exchange and a more comprehensive view of an animal’s medical history.
  • Image viewing and analysis. Veterinary PACS typically includes tools for image viewing, manipulation, and analysis. Veterinarians can zoom, measure, annotate, and apply image processing techniques to aid in their diagnosis.
  • Security and privacy. Veterinary PACS systems adhere to security and privacy standards to protect sensitive patient information and ensure compliance with relevant regulations.

Veterinary PACS has become an essential tool in modern veterinary practices, improving the efficiency of medical image management, enabling better collaboration among veterinary teams, and ultimately enhancing the quality of care provided to animals. It streamlines workflows, allows for quick access to historical images, and supports better decision-making by veterinarians, leading to improved outcomes for their animal patients.
