Resting-state FMRI confounds and cleanup (2013, unknown): “…of overall variance attributable to the underlying physiological noise increases with the signal-to-noise ratio (SNR) and so may be smaller or larger depending on voxel size and field strength (Bodurka et al., 2007; Kruger and Glover, 2001; Murphy et al., 2007; Triantafyllou et al., 2005).”
The first step for neuroimaging data analysis: DICOM to NIfTI conversion. (2016, unknown): “For example, our team has developed scripts (http://www.mccauslandcenter.sc.edu/CRNL/qa) inspired by measures described by Murphy et al. (2007) and Power et al. (2012).”
Frontostriatal Maturation Predicts Cognitive Control Failure to Appetitive Cues in Adolescents (2011, methodology): “SNR values were computed as the ratio between the mean baseline estimate from first-level general linear modeling and the standard deviation of the residual time series, as described by Murphy, Bodurka, and Bandettini ( 2007 ) and used in our previous neuroimaging work (Johnstone et al, 2005 ).”
The current state-of-the-art of spinal cord imaging: Methods (2013, background): “However, partial-Fourier acquisitions can be more sensitive to motion artifacts and have a lower signal-to-noise ratio (SNR) due to the lower number of data points sampled to produce the image (Murphy et al., 2007).”
Stability of spectral estimates in resting-state magnetoencephalography: Recommendations for minimal data duration with neuroanatomical specificity (2021, unknown): “Studies of data stability in fMRI have often recommended data durations of more than 10 minutes (Anderson et al., 2011; Birn et al., 2013; Murphy et al., 2007), which indicates a divergent pattern of intra-session stability for brain hemodynamics.”
