MRI studying confusion

By
  1. What is the difference between relaxation time, dephasing and flip angle? They all have very similar definitions.
  2. The RF pulse should be equal to 42.6 in order for the angle to change, but what if the RF pulse is more than 42.6?
  3. What really is the main difference between receive coils and T/R radio frequency coils? Why would we just not always use the T/R coils only?
  4. What would be the easiest way to compare SNR IN MRI vs X-ray?
  5. What’s the purpose of free induction decay (FID)?
  6. Do we need to know general ranges of TR/TE/ETL for the registry? Sort of like how we needed to know the WW and WL for cat scan?
  7. Why does an increase in TR cause a longer relaxation time and increase T1 information (increasing fat suppression)? I thought T1 is best shown with a short TR and TE?

AI for radiology - A survey

By
Hello folks! We are a group of students from Karolinska Institutet and Stockholm University (Sweden). We are conducting a short survey (it should not take more than 10 minutes of your time) to evaluate an Artificial Intelligence framework for evaluating medical imaging and, in particular, the effect that explainability can have on clinicians' attitudes toward it. We welcome anyone who interacts with medical imaging to take our survey, so please, feel free to do it even if you are still a student or an intern! If you know someone who works in the field, please, pass them the survey. It would help us greatly. https://bit.ly/RTEX_survey Thanks in advance to all of you! submitted by /u/francozzz [link] [comments] source https://www.reddit.com/r/Radiology/comments/r2ratp/ai_for_radiology_a_survey/
