How this list is built
Who is listed: every profile whose published research or registered trial activity places them in Radiology, read from OpenAlex topics, PubMed and ClinicalTrials.gov. This KOL finder lists the area as a whole, sub-areas included.
How the grid is ordered: enriched profiles first, then by citations on OpenAlex. The directory lists the same people with every filter and sort it offers, including recent and rising activity, and exports the result.
What is never here: scraped contact details, prescription claims data, or a judgment of anyone's influence. Every count on this page is read from a public registry and republished with its source and the date it was last published.
