About Contrast

Contrast turns medical imaging into short, visual lessons: signs, artefacts, procedures and the physics behind the picture.

Who it is for

Radiology and interventional radiology trainees, and every specialty that reads images: emergency medicine, neurology, chest, orthopaedics, internal medicine, surgery and students.

How we make every lesson

  • Real scans only. Images come from open datasets and open-access articles; no image is generated by AI.
  • Open licences. We use CC0 and CC BY images and credit every one, with the source and the licence.
  • Primary sources. Every fact is checked against a primary article or a current guideline, cited with its DOI or PMID.
  • No patient data. Images are de-identified; we remove any text that could identify a person.
  • Recognition, not treatment. Lessons teach how findings look; they do not give treatment or management advice.

The app

The Contrast app brings the lessons together with a signs atlas, image cases, IR devices in 3D, procedure simulations and mock exams. It is not public yet; join the waitlist to try it first.
