MRI physics made easy!

An introduction to the principles and basics of MRI, aimed at medical students, radiology residents, and everyone with a heart and brain for (neuro)radiology! MRI physics is not an easy topic, but I tried to make it easy by using a lot of visuals and going through it step by step. 0:00 - Introduction 1:20 - Basic MRI physics 5:55 - The external magnetic field 11:50 - The radiofrequency pulse is turned off 18:04 - Resonance and phase coherence 23:05 - The radiofrequency is switched off 24:32 - T1-relaxation 27:55 - T2-relaxation 33:14 - What causes T2-relaxation? 36:30 - T2- versus T2*-relaxation 38:04 - The free induction decay signal 40:35 - The 180° RF pulse 43:44 - 90°-180° spin echo sequence 44:51 - Repetition time & Echo Time 46:24 - Summary 48:00 - How to create tissue (image) contrast 50:46 - How to create T1-weighted images? 55:35 - How to create T2-weighted images? 58:17 - Summary Excellent sites on MRI physics: https://mriquestions.com/ This video is brought to you by the neuroradiologist: https://twitter.com/theneuroradguy/ https://www.instagram.com/the_neurora... https://theneuroradiologist.org/ #radiology #neuroradiology #neurology #medicalstudent #neuroradiologist #theneuroradiologist #MRI #medical #mri #radiologytechnologist #radiologyresident #MRIphysics #neuroradiologist #theneuroradiologist
