Tc labeled (MIBI) Flashcards
1
Q
why its tc better than tl
A
-easier availability
-better photon energy (less attenuation)
-shorter T1/2 allows greater quanities of activity
2
Q
what is mibi
A
a lg monocationic complex that incorporates Tc into atomic structure
3
Q
the uptake of MIBI is
A
passive across the myocyte membrane but not via K+ pump
4
Q
uptake is proportional to
A
regional blood flow
5
Q
blood clearence T1/2 is
A
3-5 min
6
Q
myocardial uptake at stress
A
about 1.5%
7
Q
myocardial uptake at rest
A
about 1.0%
8
Q
MIBI vial contents
A
dissolved with pertechnetate solution and heated in boiking water bath
