Thank this is the best video of playlist. Helped me a lot.

NOW I CAN CHANGE MY CAREER CHOICE, THANK YOU!

wow this helped me so much… that rephasing example with the cars was so simple but i am mindblown at how much it made it make sense!! thank you!!

[CatMedy]

thank u so much for the videos, you're best at explaining such complicated themes!😍

But, if T2 is shorter than T1, in ohter words, T2 effect decays earlier than T1 effect, how does a long TE emphasize T2 in detriment of T1?

By following the logic that T2 is shorter than T1, so the more the time passes, the greater would be T1 effect in comparison with T2, right?

[mrkarn]

is it safe to say to fire immediately a 180 pulse to have a shorter TE?

sir, when fat have short longitudinal relaxation time then why they relax quicker on z-axis in short TR

Hi! These have been so helpful! By chance, do you know when the video for Fat Saturation will be posted?

How does fat and water appear in gradient sequences?

Tissues usually have a much slower T2 time vs T1. So how come short TE isnt better for T2 times?
