Method for determining the reliability of fMRI parameters |
摘要 |
An EPI pulse sequence is performed by an MRI system which acquires images of the brain over a time interval during which the subject performs a function or is stimulated in a pattern. An fMRI parameter is calculated for each voxel which indicates those regions of the brain that are active during the study. The same acquired NMR data is employed in a jackknife method for recalculating the fMRI parameter many times and from the distribution of the recalculated values a confidence level indicator is produced. Low confidence level indicators are used to exclude regions which are otherwise indicated as active.
