A comparison between a) SENSE (SE) real, b) SE imaginary, c) SE real/imaginary, d) SE magnitude-squared operator induced correlation about the center voxel, and e) SE real, f) SE imaginary, g) SE real/imaginary, h) SE magnitude-squared estimated correlation about the center voxel over the time series of the Spherical Phantom with, i) SENSE-ITIVE (SI) real, j) SI imaginary, k) SI real/imaginary, and l) SI magnitude-squared operator induced correlation about the center voxel and m) SI real, n) SI imaginary, o) SI real/imaginary, and p) SI magnitude-squared estimated correlation about the center voxel over the time series of the Spherical Phantom. Correlations presented with a threshold of 0.15 for operators with an identity estimated voxel covariance structure assumed. Smoothing was applied with a Gaussian kernel with a FWHM of 3 voxels.
