Bo OuYang,Ying Dong,James J. ChouEcho-planar imaging (EPI) is more sensitive to image artifacts than conventional imaging for two basic reasons; these are (a) reversal of every second echo and (b) the long readout (RO) period.

完成

P. Ananda Kumar,O. M. BambawaleWith echo-planar imaging (EPI) images may be acquired in less than 1 s [98], providing many advantages relevant to clinical diagnosis. In addition to the practical virtues of faster image acquisition and reduced sensitivity to motion artifact, the technique allows investigation of physiological processes such as diffusion and perfusion.

Research Issues Using Echo-Planar Imaging for Functional Brain Imaging,ast 3 years become one of the most successful tools used to study blood flow and perfusion in the brain. Since changes in neuronal activity are accompanied by focal changes in cerebral blood flow (CBF), blood volume (CBV), blood oxygenation, and metabolism, these physiological changes can be used to produce functional maps of mental operations.
