Comparison of fMRI activation at 3 and 1.5 T during perceptual, cognitive, and affective processing
2003
NeuroImage
Preserved Fulltext
In the present study, we investigated fMRI activation at 1.5 and 3 T during visual perception, visuospatial working memory, and affect-processing tasks. ...
No difference in height or extent of activation was detected between the two scanners in the amygdala during affect processing. ...
