IMAGING CONNECTORS

PACS & VNA Connectors

2 of 8

Connect Mediloop securely with Picture Archiving and Communication Systems (PACS) and Vendor Neutral Archives (VNA) to retrieve, store and manage imaging data without replacing existing systems.

What We Synchronize
Study, series and instance metadata
Patient demographics and identifiers
Accession numbers and order references
Procedure / modality / body part information
Study dates, statuses and availability
Reports and structured data references
Tag mappings and normalization rules
Storage location and archive tier
Retrieval & Access
Unified study search

Search prior studies across multiple PACS/VNA using one Mediloop interface

Streaming access

Stream instances, thumbnails and rendered views with progressive loading

Smart caching

Pre-fetch or cache frequently used studies close to the user

Governed access

Enforce scopes, tenant context, consent and audit on every retrieval

PACS vs VNA
PACS — operational
Active clinical system for daily imaging operations
Optimized for acquisition, workflow and fast clinical access
Typically departmental or enterprise scoped
Short-to-medium operational retention
VNA — archive
Vendor-neutral long-term archive
Designed for retention, consolidation and data longevity
Multi-vendor / multi-PACS consolidation
Tiered storage across on-premises and cloud
Key Capabilities
Unified access

Search across multiple PACS/VNA through a single interface

Vendor neutrality

Operate across heterogeneous vendor environments

Metadata synchronization

Keep patient and study metadata aligned

High performance

Caching, CDN-friendly delivery and optimized bulk transfer

Intelligent routing

Route requests to the correct repository based on rules

Resilience & failover

Automatic failover and alternate repository paths

Partial-match suggestions and controlled manual review
Conflict resolution with configurable source-of-truth rules
Retry with exponential backoff
Detailed error codes and diagnostics
Dead-letter queue for failed operations
Complete audit trail for every transaction
Common Use Cases
Access prior images

Retrieve external studies for clinical context

Enterprise imaging
