    Not sure if the question banks are for you?
    If you're here, you're likely studying for a radiology physics exam. I've spent the last few months collating past papers from multiple different countries selecting the most commonly asked questions. You'll be surprised how often questions repeat themselves!
    The types of questions asked in FRCR, RANZCR AIT, ARRT, FC Rad Diag (SA), ABR qualifying Core Physics and MICR part 1 are surprisingly similar and the key concepts remain the same throughout. I've taken the most high-yield questions and answered them in video format so that I can take you through why certain answers are correct and others are not.
    Happy studying,
    Michael

    Amazing how great you are explaining all of this! I'm a MRI technician and this week Siemens workers changed our gradient coil which was broken. They explained to me the shimming process and even showed me the pieces of metal they used for it. But you made it all so much clearer! Will be watching all of your videos for sure!

  • @Sparkie075

    Brilliant analogies! Even more brilliant explanations! You just taught me a concept I, apparently, wasn’t fully understanding after years of studying. How the magnetic moments are flipping exactly.
    I always thought they flipped transversely and precessed like a top in that direction. That it flipped and spun in the same manner as it was pre-stimulation. Instead, they fan out, and at 90 degrees, the spin looks more like the face of a watch. Mind. Blown. 🤯
    I take the registry in four days, and will probably blow it away. However, I wish I’d discovered you earlier to better understand the actual practical concepts. Either way, my coworkers will come to know your tutorials well. Thanks.

    • @radiologytutorials
      @radiologytutorials  Před 9 měsíci

      Hi 👋🏼 gradient fields help us localise signal. Covered in upcoming talks. We don’t want magnetic field heterogeneity rather homogeneity to accurately localise signal based on precessional frequency and phase. We go into more depth in the next few talks 🙂

    Hi Michael, I have one question though, How can RF coil create perpendicular magnetic field? As the setup is such, the magnetic field generated by any coil can only be in longitudinal direction. BTW wonderful videos!!

    • @hannahdawson3879
      @hannahdawson3879 Před měsícem

      Forgive me if I’m wrong, but the way I understand it, the RF pulse is not creating a perpendicular magnetic field, but rather causing the protons within the longitudinal field to ‘flip’ into the transverse plane. It’s just the protons flipping, not the magnetic field!

    Dear Dr. Nel,
    Out of curiosity, did you mean "homogenous" or "homogeneous" when referring to the ideal world magnetic field? Apparently, the pair is a loved example of some essayists and grammarists. Both meanings might fit although homogeneous is probably the right one 🤓
    Thanks a million for the outstanding content.

    • @radiologytutorials
      @radiologytutorials  Před 6 měsíci +1

      Learned something today. Seems the majority of people have given up trying to keep the two separate in meaning. But yes, technically homogeneous ☺️

    Doctor you can scare us nevertheless you are recorded anyway..
    But I am still failing to make sense of how the transverse plane contribute to the t1 decay

    • @radiologytutorials
      @radiologytutorials  Před rokem +2

      Hopefully it will become clear over the next few videos. T1 decay is only determined by regaining longitudinal/ Z axis vector (which is due to tissue type and strength of magnetic field). Transverse magnetisation is completely independent of T1 decay.
