Functional brain imaging at 1.5 T using conventional gradient echo MR imaging techniques
RT Constable, G McCarthy, T Allison… - Magnetic resonance …, 1993 - Elsevier
There is considerable interest in the use of MR imaging to study brain function. Recently, it
has been demonstrated that small changes in signal intensity occur in the visual cortex in T
2∗-weighted imaging in response to appropriate visual stimuli. Similar responses to
activation have also been recorded in motor cortex as well as frontal lobes. To date most of
these studies have been carried out at very high field strength or they have used echo
planar imaging. We report our preliminary results showing that the effects of activation of …
