How It Works The old paradigm of learning clinical radiology from books or single slide images in conference is over!

Prometheus Lionhart has joined forces with Garrett Walters to create a revolutionary teaching strategy combining didactic video lectures centered on anatomy, disease process, location strategies, interdisciplinary knowledge, and one of the most powerful clinical tools of all: applied biostatistics.

Best of all, you can apply your knowledge with a growing library of real, interactive cases and skill-based challenges. Plus there are special topics including: search patterns, perception strategies, dictation, and reporting strategies.

Clinical Mastery

Totally Unique in Medical Education.  The clinical mastery platform combines in-depth didactic training with iRad- allowing you to gain knowledge and apply it immediately.

  • Didactic lesson videos build a foundation of knowledge from the ground up, with important concepts repeated to solidify retention.
  • Pathology is explored with an emphasis on anatomy and mechanism – this makes it easy to remember where to look.
  • Learn how to diagnose both basic and complex pathology, formulate a differential, and think clinically about the next appropriate step or exam.
  • The Ronin method of “these pictures get these words” makes reporting findings and understanding Radiology language easy.
  • Practice your skills using iRad – with real cases and challenging exercises.
  • The learning never stops with an ever-growing collection of videos and cases, with new content added weekly.


iRad provides a revolutionary active learning experience. We teach you how to use iRad to manipulate DICOM images and interpret real radiology cases. Each case you interpret is followed by a “Virtual Readout” delivered by talented board-certified radiologists, who are highly skilled in both clinical practice and teaching.
