Question 1

What is the fundamental architectural difference between a traditional PACS and a VNA?

Accepted Answer

PACS typically uses vendor-specific proprietary storage formats; VNA provides open, standards-based storage enabling multi-vendor access

Answer

Traditional PACS solutions often rely on proprietary storage tied to one vendor, while VNA uses open standards allowing images to be accessed by any compliant system.

Question 2

Which method provides secure DICOM image transmission over the internet or wide-area networks?

Accepted Answer

DICOM over TLS or DICOMweb over HTTPS

Answer

DICOM over TLS (Transport Layer Security) or DICOMweb over HTTPS encrypts image transmissions to ensure confidentiality and integrity over public networks.

Question 3

What does 'image lifecycle management' in a VNA refer to?

Accepted Answer

Policies governing image creation, active storage, long-term archiving, retrieval, and eventual disposition per retention rules

Answer

Image lifecycle management defines rules for how images are handled from initial acquisition through archiving tiers and final disposition according to regulatory retention requirements.

Question 4

What is 'de-identification' of medical images and why is it required?

Accepted Answer

Removing or obscuring patient-identifying information from images and headers to enable use without exposing PHI

Answer

De-identification removes PHI from DICOM images and metadata to comply with HIPAA when images are used for research, education, or cross-organizational sharing.

Question 5

What is the purpose of a national Image Exchange Network such as Carequality or CommonWell in enterprise imaging?

Accepted Answer

To enable patients and providers to share clinical images securely across different health systems nationwide

Answer

National image exchange networks like Carequality enable secure, standards-based interoperability for sharing clinical images across different health systems and EHR platforms.
