The reliability is important for functional magnetic
resonance imaging (fMRI) data. Previous study has
developed a statistical model (independence model) to
quantify the test-retest reliability with only two
states (active or inactive). More and more fMRI
experiments have detected three state regions in the
brain, including active, deactive and non-significant
regions. In order to quantify the test-retest
reliability of the fMRI data with three state regions,
this study developed the three-state independence model.
The model was applied to acupuncture fMRI data, the
results indicated that the reliability of BOLD was
higher than that of CBF.
