=========================
Filling each line of K-space takes requires a different degree of phase encoding gradient. In diagnostic imaging we need to be able to fill K-space rapidly to reduce motion artifact and keep scanning times down.
Here we will review the fast imaging sequences in MRI. First we will revisit fast spin echo imaging, then gradient echo imaging with short TRs and finally end off by discussing echo planar imaging.
These techniques fill either large regions of K-space (multishot imaging) or K-space in it’s entirety (single shot imaging).

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

Hi! First of all, I'd like to thank you for creating a series that actually _explains_ MRI in a way that you are actually able to understand the concepts, after trying to grasp the idea of it from the books (which, by the way, seem like the authors wrote them for themselves, not for the reader newbies :) ) My whole department used your lectures and we're really grateful. Our attendings took a look at them after suddenly all our residents became super clever and your lectures became a staple of our MRI rotation. :) Do you plan on adding more videos? I've been checking everyday for a new episode. Especially about DWI. I hope you're doing well, and thank you so much once again!

Wow, what an honour! Thanks for such a kind message. Planning to film the new videos soon. I’m away from home for another week and will film once I’m back 🙂 have made the diagrams for DWI/ADC. Can’t wait to share the next few videos with you all. All the best from South Africa 🇿🇦

Thanks a lot for these set of videos, your effort explaining both visually and with your talks has helped me tremendously!! Regarding this video I have the following doubt: During the GE-EPI, would'n we need large PEG at the beginning right after the intial flip angle pulse? Otherwise we would just measure half of the k-space no?
