19:35 But the omegas arent the same for all atoms otherwise they wouldnt dephase so a rotating frame is just the average omega0 and the linewidth of the omega spec is just giving the decay time of the frequency that is still omega0. So to even think about a rotating frame is still making sense?

38:15 Note: The Nyquist frequency is as stated in 52:45 is half of the Sampling frequency \omega_s. Thus the total frequency space will vary between (- \omega_s/2) to (+ \omega_s/2). Where \omega_s = Sampling Frequency.

TB has a greater signal at TE, according to the amount of T2 weighting evaluated at that time. b. TB will still have the greater signal c. The greatest contrast would be achieved at the greater T2 of all tissues, therefore at TE = 40ms 4. TE = 7.699ms **I will do a follow-up later

I’ll be having my Brain MRI tomorrow. My doc prescribed one Lorazapam ~ I’ll be taking my “provided” transportation. Curious and a bit worried if I’ll be “out of it” by the time I’ll be getting picked up afterwards. I already have issues of falling asleep anywhere and everywhere. Falling a few times already. Oh no!! I also wear a Dexcom G6 monitor on my Arm~ for my extreme low blood sugars that drop frequently. I’ll need to remove before scan , right!???

15:12 So you´re basically telling me that I FINALLY found that one in 10.000 videos that is made by someone who knows how to solve that mystery and then he doesn´t explain this. Can you PLEASE make a follow-up video before I completely lose myself? I have literally looked for something that explains this for OVER HALF A YEAR and now you don´t explain it. That is the only reason I even clicked this video. I. Want. To. KNOW. Yo no offence dude, seems like you´re doing a good job here but at some point I will go insane if I keep looking for that answer. Which means I have to stop looking. That can´t be the answer
@yrusb3 ай бұрын
Okay I think I got it, I guess it´s a good thing you mentioned the transition states and the ket-vectors oO So correct me if I´m wrong, but the transition states are probably complex-valued linear combinations of the ket-vectors in such a way that there are only two possible linear combinations for eigenvectors which lead to spin up/spin down and the transition states with the flip-angels aren´t you´re standard boring angles but actually are complex-valued angles. Right or wrong?

@36:12 , it seems that the labeled exponentials for phase encoding and frequency encoding are flipped? based on the preceding sections, frequency encoding should be the one with time dependence and the phase encoding term should be the one where the gradient is only turned on for some time tau
