Answers are drawn from this dictionary entry and the rest of the CASRAI corpus, with a link to every source.

Answers are AI-generated from CASRAI’s own published pages and can be wrong, so check the linked sources before relying on one; your question is logged without personal data — never sold, never used to train a third-party model — to show us what CASRAI is missing, so please do not type personal or confidential details.

Worked examples

A Midjourney-generated cover illustration

Counter-examples

Looks similar, but isn't

Not an instance
A real microscopy image with AI-enhanced contrast (this is image processing, not a synthetic image — but the processing must still be disclosed)

Editorial commentary

Synthetic images in scientific publications must be disclosed and clearly distinguished from observed images (microscopy, imaging, photography). Many journals now prohibit AI-generated images in scientific figures except where the image generation itself is the subject of study.
