Nuclear medicine de-identification is the removal of patient identifiers from the file. UK GDPR Art. 9 and the DPA 2018 govern health data. anonym.plus runs it on your device. The uptake findings stay, but no person is named.
When this applies
A PET case fits a research set. The findings can stay, yet the name, the dose log, and the dates have to be hidden first.
How anonym.plus handles it
- Open the file (PDF, image, or scan) on your machine.
- Local OCR reads any text printed on the view.
- The tool flags names, dates, IDs, and the dose line.
- Review each flag and keep the uptake values.
- Swap each ID for a token, or box it out.
- Save the clean study. The source stays with you.
What you need to provide
- The file (PDF, JPEG, PNG, or image scan).
- An operator: Replace (swap), Redact (remove), or Mask (partial).
- Optional: a name map for serial studies.

Compliance achieved
- Anonymisation under UK GDPR Art. 9 & DPA 2018.
- Once truly anonymous, the file leaves UK GDPR scope under Recital 26.
- Assessed against the ICO motivated-intruder test.
- Working files are kept safe with AES-256-GCM.

Limitations & cautions
Dose logs may carry a name beside the tracer details. The tool flags those names. Confirm the result, since a missed log line undoes the rest.
Frequently asked questions
Will tracer and uptake values be kept?
Yes. Those are clinical numbers, not patient IDs. They stay in place so the study still shows the uptake pattern.
Are dose-log names flagged?
Yes. A name in the dose line is flagged like any field. You decide whether to keep the technologist or hide them.
Can I link a baseline and a follow-up?
Yes. A name map gives one patient a stable token. Serial studies stay grouped with no real name shown.
