=========================
Let's discuss nuclear magnetic resonance. First we will look at what nuclear spin is and how it determines the magnetic moment. Then we'll see how non zero spin atomic particles behave in an external magnetic field. We'll discuss the role of the gyromagnetic ratio and magnetic field strength on precession frequency, using the Lamour equation to calculate this relationship. Lastly, we discuss resonance secondary to the application of a radiofrequency pulse.

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
