,What fat suppression technique nulls T1 values with a short inversion time, and is
not recommended after giving gadolinium, as it obscures gadolinium's effects of
shortening the T1 relaxation time?

D) STIR
D) STIR
_______ refers to an action initiated by an event; while _____ is a threshold
allowing data through under certain conditions.
