Which statement best describes DICOM in the health care IT context?

• A. The international standard for medical images and related information (ISO 12052), vendor-independent; developed by the American College of Radiology and the National Electronic Manufacturers Association.
• B. A digital streaming protocol for telehealth sessions.
• C. A method for electronic prescribing.
• D. A personal health record format.

Answer: (A)

DICOM is the standard that makes medical imaging data interoperable across different systems. It defines how images and their related information are formatted, stored, and transmitted so devices and software from various vendors can work together. This vendor-independent approach means a CT or MRI scan from one manufacturer can be read, stored, and viewed by another vendor’s PACS or clinical viewer without compatibility issues, which is essential for seamless radiology workflows. DICOM packages not just the image data but rich metadata—patient identifiers, study details, imaging modality, acquisition parameters—so clinicians have the full context needed for accurate interpretation and integrated care. It’s developed by the American College of Radiology and the National Electrical Manufacturers Association and is published as an ISO standard, underscoring its global adoption. It’s distinct from a digital streaming protocol for telehealth, an electronic prescribing method, or a personal health record format.
