Hi, I’m PD Dr. med. Christoph Agten, an MSK radiologist and mentor. I've published 40+ research papers in top MSK journals, written the bestselling book SPEED MSK, and completed MSK fellowships in Zurich and New York. As a full-time teleradiologist specializing in MSK MRI, I started this channel to help radiologists around the world master MSK.
