A novel gamma GLM approach to MRI relaxometry comparisons
PURPOSE: To demonstrate that constant coefficient of variation (CV), but nonconstant absolute variance in MRI relaxometry (T (1), T (2), R (1), R (2)) data leads to erroneous conclusions based on standard linear models such as ordinary least squares (OLS). We propose a gamma generalized linear model...
