CIIP Enterprise Imaging and Vendor Neutral Archives 2 — Questions and Answers
Question 1: Which migration strategy best minimizes clinical disruption when transitioning from a legacy PACS to a VNA?
- Big-bang migration — moving all data in a single weekend cutover
- Deleting all legacy data and starting fresh with new studies only
- Phased or parallel migration — running legacy and new systems concurrently during transition (Correct answer)
- Migrating only studies from the past 30 days and discarding older archives
Correct answer: Phased or parallel migration — running legacy and new systems concurrently during transition
Phased or parallel migration allows clinicians to access both legacy and new systems simultaneously during transition, reducing risk and minimizing workflow disruption.
Question 2: Which DICOM service class operations are used to query and retrieve images from a VNA?
- C-FIND and C-MOVE (or C-GET) (Correct answer)
- HL7 ORM and ORU messages
- SNOMED CT lookup and ICD-10 mapping
- TCP/IP ping and ICMP traceroute
Correct answer: C-FIND and C-MOVE (or C-GET)
C-FIND is used to query a DICOM server for matching studies based on search criteria, while C-MOVE or C-GET retrieves the actual image objects.
Question 3: What does 'image federation' enable in an enterprise imaging environment?
- Consolidating all images into a single centralized monolithic server
- Accessing images distributed across multiple repositories through a unified query interface without moving data (Correct answer)
- Restricting image access to a single clinical department
- Automatically deleting duplicate studies across the network
Correct answer: Accessing images distributed across multiple repositories through a unified query interface without moving data
Federation allows a single query interface to search and retrieve images from multiple distributed repositories without physically centralizing or migrating the data.
Question 4: What is a 'zero-footprint viewer' in the context of enterprise imaging?
- A diagnostic workstation with no local disk storage
- A viewer that displays only low-resolution image thumbnails
- A PACS viewer requiring a large software client installed on every workstation
- A web browser-based viewer requiring no client-side software installation (Correct answer)
Correct answer: A web browser-based viewer requiring no client-side software installation
Zero-footprint viewers run entirely within a web browser using HTML5/WebGL, requiring no local software installation and enabling access from any device.
Question 5: What is the primary role of an Image Exchange Platform (IEP) in enterprise imaging?
- To automatically generate radiology reports using AI
- To enable secure electronic sharing of medical images between different healthcare organizations (Correct answer)
- To manage radiologist work schedules and reading assignments
- To replace PACS systems in all clinical departments
Correct answer: To enable secure electronic sharing of medical images between different healthcare organizations
An IEP facilitates secure, standards-based electronic exchange of medical images between different healthcare organizations, replacing physical media such as CDs.
Question 6: What is the most significant technical challenge during migration of image data from a legacy PACS to a VNA?
- Installing new radiology reading workstations across all sites
- Training radiologists on new report dictation templates
- Ensuring data integrity, DICOM header accuracy, and metadata reconciliation during transfer (Correct answer)
- Obtaining new vendor licenses for the target VNA system
Correct answer: Ensuring data integrity, DICOM header accuracy, and metadata reconciliation during transfer
Maintaining the integrity of DICOM data, especially accurate metadata reconciliation and completeness verification during migration, is the most critical technical risk.
Question 7: What is the IHE XDS-I (Cross-Enterprise Document Sharing for Imaging) profile designed to support?
- Automatic generation of radiology reports from AI-analyzed images
- Compressing DICOM files for transmission via standard email
- Scheduling imaging appointments across multiple enterprise departments
- Sharing imaging documents and objects across different enterprise systems using standard IHE profiles (Correct answer)
Correct answer: Sharing imaging documents and objects across different enterprise systems using standard IHE profiles
XDS-I extends the IHE XDS document sharing profile to include diagnostic imaging objects, enabling cross-enterprise sharing of images and associated reports.
