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.
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!
Don't be nervous. You are cool.
The best explanation
wow ! excellent explanation.

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