Manual authority hub
Radiology questions answered in plain English
This hub collects manually curated RadDx pages for the questions patients actually ask after reading a scan: what a phrase means, whether imaging can show something, when worry is reasonable, and why one imaging test may be used instead of another.
These pages are intentionally small in number. They are built to reinforce the findings and report-phrase ecosystem, not to auto-generate broad clusters.
