Single subject fMRI test–retest reliability metrics and confounding factors

Krzysztof J. Gorgolewski, Amos J. Storkey, Mark E. Bastin, Ian Whittle, Cyril Pernet
2013 NeuroImage  
While the fMRI test-retest reliability has been mainly investigated from the point of view of group level studies, here we present analyses and results for single-subject test-retest reliability.  ...  The contributions of confounding factors (scanner noise, subject motion, and coregistration) were investigated using multiple regression and relative importance analyses at each step.  ...  Indeed, global effects in context of single subject test-retest reliability have also been a topic of a recent work by Raemaekers et al., 2012.  ...
