Structured Knowledge for All
Doctreen was born from a conviction held by Michel Benisty, a radiologist: clinical reasoning can be modelled so that it becomes accessible, transferable and reproducible. It is the foundation of our medical knowledge base, and of Spark, which 400 active radiologists use today to write their reports (August 2026; active = Spark used in at least 75% of sessions).
