To be clear, when we measure longitudinal relaxation, it isn't described quite by exponential growth (M = M_0*e^t/r). Rather, it's described by exponential recovery (M = M_0*(1-e^-t/r)) so that as time goes on (and relaxation is complete), the signal returns to the maximal magnetization rather than increasing forever.
The best explanation
Don't be nervous. You are cool.
You are AMAZING!!!!! thank you so much - very comprehensive and detailed.
Excellent job at explaining these details at the level that a beginner can understand!
Excellent
wow ! excellent explanation.

Brilliant explanation
did anybody get why when using short or long TR and TE we get different dependencies?
