Neuroimaging Flashcards
1
Q
eloquent tissue
A
functional tissue
2
Q
Fluid Attenuated Inversion Recovery (FLAIR)
A
imaging that reflects specific type of water in tissue–can enhance tumor contrast
3
Q
Functional MRI relies on what for signal?
A
vasodilation–oxygenated blood has a magnetic character
4
Q
What does the magnetic field influence in a fMRI
A
the frequency at which water protons will transmit
5
Q
diffusion tensor imaging (DTI)
A
is based on water diffusion–so captures white matter tracts
6
Q
intra-op guidance
A
virtual reality of the brain while the surgeon is operating
