My channel is aimed particularly at medical students, (prospective) MTRs and training assistants in radiology - but of course anyone else who is interested is also welcome! #radiologie #radiology #radiologyresident #radiologytechnologist #radiologytutorial #radiologystudent #radiologytech #radiologylife #Lernrad ▬ For further learning - my online learning platform ▬▬▬▬▬▬▬▬▬▬▬▬ ????Do you want to continue learning?????‍???? Then take a look at www.lernrad.com! ???? This is my online learning platform for medical students, radiologists and MTRs - because high-quality digital teaching is a real matter of the heart for me ???????? ????I will continue to provide you with free content here on YouTube - but if you want more and want to go into depth with our effective "active learning" concept directly on the clinical case and take something with you for life, then I warmly invite you to take a look at our diverse courses. Students get a 75% discount (and DRG members 50%)! ???? At www.lernrad.com we also offer free introductory courses on the technical basics: https://www.lernrad.com/basics-kurse/, which combine my technology YouTube videos with interactive elements and quiz questions to create a short course. ▬ Even more videos ▬▬▬▬▬▬▬▬▬▬▬▬ Subscribe to my channel: https://bit.ly/bettinabaessler-subscribe All videos from my channel: http://bit.ly/bettinabaessler ▬ Social Media ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ Website: www.lernrad.com LinkedIn Bettina Baeßler: https://bit.ly/bettinabaessler-linkedin LinkedIn Lernrad GmbH: linkedin.com/company/lernrad-gmbh Facebook: facebook.com/LernRad.GmbH ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
