In DR, which statement accurately describes the function of DICOM within imaging workflows?

• A. DICOM governs privacy policies for hospital networks.
• B. DICOM is used for film development.
• C. DICOM defines data structure and exchange of imaging data.
• D. DICOM sets mandatory patient consent forms.

Answer: (C)

DICOM provides the rules for how medical images and their related information are structured and exchanged across different devices and software in the imaging workflow. It standardizes the format of the image data, patient and study metadata, and the communications needed to move that data between modalities, PACS, RIS, and viewing workstations. This consistency allows a radiology department to capture an image on one machine and reliably store, retrieve, and display it anywhere in the system, facilitating seamless interoperability. DICOM also defines the network services and protocols used to transfer and query imaging data, keeping the workflow connected and efficient.

Privacy policies, film development, and patient consent forms fall outside the scope of DICOM. Privacy rules are governed by regulatory frameworks and institutional policies, film development relates to traditional analog processes, and consent forms are legal documentation rather than technical standards. The essential function here is providing a standardized data structure and exchange framework that enables interoperable imaging workflows.
