Frequently Asked Questions (FAQ)

This section addresses common questions

Q: How does pseudonymization work in ADIT?

A: ADIT uses the dicognito library to:

  • Remove identifying information from DICOM headers
  • Replace patient names/IDs with provided pseudonyms
  • Add trial information if specified
  • Maintain consistency across multiple studies for the same patient

Q: What DICOM tags are anonymized?

A: ADIT anonymizes standard identifying tags including:

  • Patient Name, Patient ID, Patient Birth Date
  • Referring Physician, Institution Name
  • Other tags according to DICOM anonymization profiles

The following date/time tags are preserved to maintain clinical context:

  • Study Date, Study Time
  • Series Date, Series Time
  • Acquisition Date/Time
  • Content Date/Time

Q: Does ADIT preserve patient age during anonymization?

A: Yes. While PatientBirthDate is anonymized (shifted by a random offset), ADIT uses the dicognito library which preserves the patient's age relative to the study date. This means an 80-year-old patient will still appear as 80 years old in the anonymized data, not as a 20-year-old. This is important for maintaining clinically relevant information while protecting patient identity.

Q: Which DICOM protocols are supported for my server?

To determine which DICOM protocols are supported by a server, consult the server's DICOM Conformance Statement.
