Which system is primarily used for long-term storage of digital image data?

The Picture Archiving and Communication System (PACS) is primarily used for long-term storage of digital image data. PACS is a comprehensive medical imaging technology that facilitates the storage, retrieval, management, distribution, and presentation of medical images. It allows radiologists and healthcare professionals to access imaging studies from various modalities without the need for physical films, which significantly enhances efficiency and provides easier access to patient data.

PACS is specifically designed to handle large volumes of imaging data and incorporates features for managing long-term archives, ensuring that images can be stored efficiently and retrieved quickly for future reference. This system not only aids in the storage of images but also streamlines workflows in medical facilities by integrating with other information systems, thus playing a crucial role in the management of digital imaging.

The other mentioned systems, while important in their contexts, do not serve the primary function of long-term storage for digital medical images. For instance, Electronic Health Record (EHR) mainly focuses on storing comprehensive patient health information, DICOM is a standard for image data interchanges and does not function as a storage solution itself, and ICD-10 pertains to coding and classification of diseases, which is unrelated to the storage of imaging data.
