Tissue Relaxation Flashcards
1
Q
what happens during tissue relaxation?
A
Recovery of the longitudinal magnetisation
Decay of the transverse magnetisation
2
Q
Spin lattice relaxation
A
H nuclei in tissue giving up energy to surrounding tissue environment or lattice.
3

How much faster is T1 than T2
A
5-10
6
Q
FID
A
free induction decay
7
Q
why focus on H nucleus
A
Strongest magnetic field compared to other MR active nuclei.
Most abundant in the body
