Conjunction revisited
收藏 引用
NEUROimage 2005年 第3期25卷 661-667页
作者: Friston, KJ Penny, WD Glaser, DE Univ Coll Dublin Wellcome Dept Imaging Neurosci London WC1N 3AR England Univ Coll Dublin Inst Cognit Neurosci London WC1N 3AR England
The aim of this note is to revisit the analysis of conjunctions in imaging data. We review some conceptual issues that have emerged from recent discussion (Nichols, T., Brett, M., Andersson, J., Wager, T., Poline, J.-... 详细信息

An improved theoretical P value for SPMs based on discrete local maxima
收藏 引用
NEUROimage 2005年 第4期28卷 1056-1062页
作者: Worsley, KJ McGill Univ Dept Math & Stat Montreal PQ H3A 2K6 Canada Montreal Neurol Inst McConnell Brain Imaging Ctr Montreal PQ H3A 2B4 Canada
We present a new continuity correction to the P value for local maxima of a statistical parametric map that bridges the gap between small FWHM, when the Bonferroni correction is accurate, and large FWHM, when random f... 详细信息

Statistical tests for fMRI based on experimental randomization
收藏 引用
NEUROimage 2003年 第2期19卷 226-232页
作者: Raz, J Zheng, H Ombao, H Turetsky, B Harvard Univ Sch Med Dept Hlth Care Policy Boston MA 02115 USA Univ Penn Div Biostat Philadelphia PA 19104 USA Univ Illinois Dept Stat Urbana IL USA Univ Penn Brain Behav Lab Philadelphia PA 19104 USA
Statistical parametric mapping (SPM) analysis of fMRI data requires specifying correctly the temporal and spatial noise covariance structure. This is a difficult if not impossible task. When these assumptions are not ... 详细信息

Functional magnetic resonance imaging (fMRI) "brain reading": detecting and classifying distributed patterns of fMRI activity in human visual cortex
收藏 引用
NEUROimage 2003年 第2期19卷 261-270页
作者: Cox, DD Savoy, RL Rowland Inst Sci Inc Cambridge MA 02142 USA Athinoula A Martinos Ctr Struct & Funct Biomed Im Charlestown MA 02129 USA HyperVis Inc Lexington MA 02420 USA
Traditional (univariate) analysis of functional MRI (fMRI) data relies exclusively on the information contained in the time course of individual voxels. Multivariate analyses can take advantage of the information cont... 详细信息

A model-based method for retrospective correction of geometric distortions in diffusion-weighted EPI
收藏 引用
NEUROimage 2002年 第1期16卷 177-199页
作者: Andersson, JLR Skare, S Karolinska MR Res Ctr S-17176 Stockholm Sweden
The self-diffusion tensor may be calculated from several echo-planar image acquisitions preceded by different diffusion gradients. Unfortunately, these diffusion gradients cause geometric distortion that must be corre... 详细信息

Improved parametric image generation using spatial-temporal analysis of dynamic PET studies
收藏 引用
NEUROimage 2002年 第3期15卷 697-707页
作者: Zhou, Y Huang, SC Bergsneider, M Wong, DF Univ Calif Los Angeles Sch Med Dept Mol & Med Pharmacol Los Angeles CA 90095 USA Univ Calif Los Angeles Sch Med Div Neurosurg Los Angeles CA 90095 USA Univ Calif Los Angeles Sch Med Brain Injury ReS Ctr Los Angeles CA 90095 USA Johns Hopkins Med Inst Russell H Morgan Dept Radiol & Radiol Sci Baltimore MD 21287 USA
The value of parametric images that represent both spatial distribution and quantification of the physiological parameters of tracer kinetics has long been recognized. However, the inherent high noise level of pixel k... 详细信息

Sexual dimorphism in the corpus callosum: A characterization of local size variations and a classification driven approach to morphometry
收藏 引用
NEUROimage 2002年 第3期17卷 1504-1511页
作者: Pettey, DJ Gee, JC Univ Penn GRASP Lab Dept Comp & Informat Sci Philadelphia PA 19104 USA Univ Penn Dept Radiol Philadelphia PA 19104 USA
We present two complementary quantitative approaches to the problem of characterizing morphometric variations between two distinct populations. The case presented focuses solely on local size variations, but the gener... 详细信息
