Reconciliation
Match orders using accession number, procedure and patient identity
Detect duplicates and conflicting orders
Validate patient demographic consistency
Link procedure / body part / modality correctly
Track status changes with full audit trail
Alert on unmatched, orphaned or stale imaging studies
Messaging Flows
| Source → Destination | Message / Standard | Purpose |
|---|---|---|
| HIS / EHR → RIS | ORM / FHIR ServiceRequest | Create imaging order |
| RIS → Modality | DICOM C-FIND (MWL) | Provide scheduled procedure |
| Modality → RIS | MPPS N-CREATE / N-SET | Update acquisition status |
| RIS → PACS | Storage commitment / routing context | Coordinate study storage |
| PACS → Mediloop | DICOMweb / metadata sync | Expose study and metadata |
| RIS / reporting → Mediloop | HL7 ORU / FHIR DiagnosticReport | Return result/report |
Key Benefits
Right patient, right exam, right time
Eliminates manual re-entry at modality
Reduces wrong-patient / wrong-order risk
End-to-end visibility and traceability
Faster workflow and better throughput
Accurate reporting and analytics
Supports enterprise and multi-site imaging
Best Practices
Use unique accession numbers
Keep patient demographics synchronized
Validate worklist data before acquisition
Monitor MPPS for completeness
Implement alerts for exceptions and errors
Regularly reconcile orders and studies
Common Pitfalls
Missing or reused accession numbers
Mismatched patient demographics
Duplicate or conflicting orders
Incomplete procedure mapping
MPPS not sent or lost
Timezone / clock misalignment
