CMR Flashcards
1
Q
type of CMR sequence
A
Double inversion recovery
is Dark
“black blood”
2
Q
A
GRE (SSFP)
“bright blood” = flow related enhancement
3
Q
what CMR sequence is best for evaluating the anatomy of the heart
A
Fast spin echo
4
Q
typical imaging time post contrast in CMR
A
10-30 min
5
Q
typical myocardium inversion times
A
175-250 ms
6
Q
for LGE in CMR what happens if you imaging too early?
A
overestimation of infarct
7
Q
in a double inversion recovery, what 180 deg pulse is selective?
A
the second one
The first inverting pulse is spatially non-selective, while the second pulse is spatially selective.
8
Q
In CMR LGE if you image too late, what can happen?
A
UNDERESTIMATE infarct
too much wash out of scar and poor signal to noise ratio
