How do I choose between different PACS for veterinary imaging systems for a multi-site animal hospital?

Choosing a PACS for a multi-site veterinary hospital is mostly about matching the system to your workflow, modalities, sites, and support model—not just image storage. Here’s a practical way to compare options.

1) Start with your use cases

List what the system must support:

• Sites and scale

  • How many hospitals/branches?
  • Central imaging reading vs. local reading?
  • Expected growth over 3–5 years?

• Modalities

  • X-ray, ultrasound, CT, MRI, fluoroscopy, endoscopy, dental, specialty imaging?
  • Need for DICOM and non-DICOM ingestion?

• Users

  • Radiologists, general practitioners, specialists, techs, interns?
  • Need role-based access across sites?

• Workflow

  • Are studies read in real time or asynchronously?
  • Do you need worklists, priors, comparison tools, and reporting?
  • Is teleradiology part of the plan?

2) Decide on deployment model

For multi-site veterinary groups, the big decision is usually:

• Cloud PACS

  • Easier to roll out to multiple sites
  • Less on-site infrastructure
  • Better for centralized access and remote reading
  • Check internet dependency, upload times, and subscription costs

• On-prem PACS

  • More control over data and network
  • Can be faster inside the local network
  • Requires servers, backups, patches, IT support

• Hybrid

  • Local acquisition at each clinic with centralized archive/viewing
  • Often a strong fit for multi-site veterinary groups

3) Key selection criteria

A. Multi-site access and performance

Make sure it supports:

• One patient/study archive across all locations
• Fast retrieval of priors from other sites
• Concurrent access without lag
• Site-specific routing or local caching
• VLAN/VPN support if needed

B. Veterinary-specific workflow

Vet imaging differs from human radiology, so confirm:

• Species/breed fields, custom patient metadata
• Flexible patient naming and ID handling
• Support for owner info and referring vet info
• Side-by-side comparison for serial follow-ups
• Presentation for orthopedic, dental, and specialty cases
• Multi-patient households and duplicate-record handling

C. Viewer quality

Evaluate the viewer for:

• Measurement tools, window/level, MPR for CT/MRI
• Hanging protocols
• Mobile/web viewer for clinicians at other sites
• Annotation and key image capture
• Ease of use for non-radiologists

D. Reporting and communication

Look for:

• Structured or free-text reporting
• Voice dictation integration
• Report templates
• Critical result notification
• Ability to send reports back to EMR/PIMS
• Audit trail of who viewed and edited what

E. Integration with PIMS/EMR and modalities

This is often the real bottleneck. Ask:

• Can it integrate with your practice management system?
• Does it support HL7, DICOM, or API integrations?
• Can it auto-route studies from imaging modalities?
• Can it handle label/ID consistency across sites?

F. Security and compliance

Even in veterinary settings, you want strong security:

• User authentication and role-based permissions
• Encryption in transit and at rest
• Audit logs
• Backup and disaster recovery
• Data ownership and export rights
• SSO/MFA if your group uses it

G. Support and implementation

For multi-site systems, vendor support matters as much as features:

• Onboarding and migration support
• Training for staff at every site
• Uptime/SLA commitments
• Help desk hours and response times
• Local partner presence if hardware is involved

4) Ask vendors the right questions

Use these in demos:

1. How do you handle multi-site image access and priors?
2. What happens if one site’s internet goes down?
3. How do you integrate with our PIMS and modalities?
4. Can we customize species/patient fields and workflows?
5. How long does retrieval take for large CT/MRI studies?
6. What backup and disaster recovery options are included?
7. Can we export all studies and metadata easily if we leave?
8. What training is included for each site?
9. What are the total costs over 3–5 years?
10. Can we test the system with real cases from each site?

5) Compare total cost of ownership

Don’t compare license price alone. Include:

• Subscription or maintenance fees
• Storage growth
• Implementation and migration
• Interface fees
• Hardware/network upgrades
• Training and support
• Backup/disaster recovery
• Future expansion costs

6) Run a pilot

Before committing:

• Test with one or two representative sites
• Use real workflows and real studies
• Include techs, doctors, and admins in the evaluation
• Measure:
  • time to upload
  • time to open priors
  • ease of reporting
  • reliability
  • user satisfaction

7) A simple decision framework

If you want a quick shortcut:

• Choose cloud/hybrid if you need easy multi-site access, centralized reading, and lower IT burden.
• Choose on-prem if you have strong internal IT, strict control requirements, or need local speed and resilience.
• Prioritize integration and workflow over flashy viewer features.
• Choose the system your clinicians will actually use well every day.

8) Best practice for multi-site veterinary groups

A strong setup is often:

• Central PACS archive
• Local modality acquisition at each site
• Web viewer for all clinicians
• Standardized patient/study naming conventions
• Integrated reporting and PIMS workflow
• Reliable offsite backup and disaster recovery

If you want, I can also give you:

1. a vendor comparison checklist,
2. a scorecard template, or
3. a shortlist of PACS features specifically for veterinary groups.
