In case a study on PACSonWEB deviates from the corresponding study on the local PACS system, an anomaly will be registered. In this case, the anomaly is clearly indicated within the study page (5. PACSonWEB study page).
When opening the study administration pages for a study that has an anomaly registered, the anomalies tab will be displayed automatically and the label will be marked in orange.


The data of each listed anomaly are the data at the moment the anomaly was registered.

If patient or study data have been modified after the registration of the anomaly, these modifications will NOT be taken into account in the anomaly.


Anomalies on study level

The following anomalies will be reported:

  • national number in DICOM files differs from HL7 information
  • date of birth in DICOM images differs from HL7 information
  • no or incorrect date of birth registered
  • number of images in PACSonWEB differs from the number of images in the local PACS (taking into account any applied filtering)
  • national number already registered with another patient through DICOM
  • image or HL7 message received with the same study instance EUID or accession number but with other patient ID 
  • research with patient without ID is changed to a patient with ID via DICOM or HL7

Anomalies on patient level

The following anomalies will be reported:

  • Multiple internal patient IDs have been registered for a single patient
  • Received national number already linked to another patient
  • Date of birth differs from date of birth that was registered with a previous exam
  • national number already registered with another patient through HL7


For each registered anomaly, the following information is shown: 

  • date and time when the anomaly was registered
  • the anomaly type + the required access level of a user to be able to open the study
  • a description of the anomaly
  • the possible corrective measures


In case a national number was registered for two different patients, it will be possible to assign this to the first patient, the second patient or to merge both patients.

For the latter option, the following screen is displayed to perform the merge in a controlled way:

Once a solution has been selected, it will be marked in green. When hovering the cursor over the label, it is displayed by whom and when the selected solution was applied.
In case all registered anomalies have been marked as solved, the notification will no longer be displayed on the study page and the label 'Anomalies' on the study administration pages will no longer be marked in orange.


All modifications with regard to anomalies on study level are registered in 'Study Logging' (5.3.6.5 Study logging).
All modifications with regard to anomalies on patient level are registered in 'Study Logging' (5.3.6.6 Patient logging).
