Content and Source Policy

1. Medical accuracy comes first

A value we are not sure of is not changed; it is first verified against a source or marked "review pending". A value whose source cannot be found is not deleted before checking where else it appears in the book and questions.

2. The most current source

• For every medical and technical statement the most recent version of the topic is sought first: guideline, update or joint EANM-SNMMI document.
• If an older source is used, it is confirmed that no newer document has replaced it, and the source is cited with its year of publication.
• Guidelines are cited by name; each clinical chapter ends with a list of current guidelines for that chapter with verified links.
• Numbers that may change over time (e.g. approval status, frequencies) are given as "reported" and dated.

3. Conflicting sources

If sources conflict and the sources do not settle the question, the value is not changed; the conflict is recorded and the decision is left to the author. Until then, both views may be given in the text with their sources.

4. Numbers, figures and animations

• Physics and dosimetry values are calculated from real data (e.g. ENSDF decay data, NIST XCOM/ESTAR/ASTAR, guideline tables).
• Drawings that are not to scale or are representative are labelled as such; any difference from the book is explained on the animation page.
• Each animation has a source line.
• Drawings of organs and processes are checked against textbooks and reliable references.

5. Copyright

Guideline and checklist text is not copied; information is written in our own words with its source. Figures published elsewhere are not used; every figure on the platform was produced for it.

6. Changes and corrections

• Every content change is recorded in the change log together with its source.
• Source-verified corrections are made in the Turkish and English text together, and related figures, animations and questions are updated at the same time.
• Important changes visible to users are listed with their date on the What's new page; medical content corrections are marked separately.
• Medical change suggestions arising from usage data or feedback are never published automatically; they need approval from a physician editor. Visual and technical fixes (overlapping text, overflow, spelling) can be made directly.

7. Artificial intelligence

AI (Claude) is used in content preparation and development; how and within which limits is explained in the AI Notice and on the "AI and Claude" page. The AI does not estimate numbers and shows only verified sources.

8. Limitations

Guidelines may be applied differently between countries and institutions; the information on this platform is for education and does not replace local protocols or clinical assessment.
