=========================

Contrast in MRI images comes from differences in T1 and T2 relaxation rates in tissues. We can select TR and TE values that will preferentially highlight either T1 or T2 differences. In this talk we review T1 and T2 relaxation as well as Echo time and Repetition time. We finish off by looking at how we can select TR and TE times that allow for contrast in the image to be predominantly from the density of free protons within the tissues.

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
