Analysis of Susceptibility Effects by Variation of Imaging Modes and Tilting Angles in TRFGE and CGE Sequences for fMRI
뇌기능 영상을 위한 TRFGE, CGE 기법에서 이미징 모드와 기울임 각의 변화에 따른 자화율 효과의 해석
Abstract
fMRI, functional MRI introduced recently appears based on the gradient echo technique which is sensitive to the field inhomogeneity developed due to the local susceptibility changes of blood oxygenation and deoxygenation. Common to all the gradient echo techniques is that the signal due to the susceptibility effects is generally decreased with increasing inhomogeneity due to the
