    The return of net magnetization in the longitudinal plane does not give off a signal. This means that T1 cannot be measured directly. Please, tell, how T1 is actually measured

    Before even watching this video I'm going to say the fact that it's over 40 minutes long is VERY promising. It tells me the author(s) didn't cut any corners or dumb anything down for the sake of appealing to typical KZreadrs. That shows some real integrity, and I respect the heck out of such integrity. I can't stand it when a video claims to explain an incredibly complex subject that requires a layperson have some background knowledge in a lot of fields in 5 minutes.
