This study evaluated inter-vender reliability and
inter-session reliability of rsfMRI by using temporal
signal-to-noise ratio (tSNR) and connectivity of
default-mode network (DMN).Although tSNR of rsfMRI was
relatively good-to-excellent on three different 3-T MRI
(from three different venders) on two different
occasions, some inter-vender and inter-session
differences in connectivity of the DMN were observed.
Therefore, researchers using rsfMRI should be aware of
these limitations especially in case of longitudinally
designed multicenter studies.
