Renal BOLD-MRI has been proposed as a method of
functional renal imaging. Baseline values of T2* (R2*)
and change in T2* in the kidneys after administration of
a diuretic such as furosemide have been reported to
correlate with severity of kidney disease. However,
other published data shows no correlation between renal
R2* and severity of chronic kidney disease. Among the
potential confounding factors for accurate T2*
quantification are B0 inhomogeneities that can result in
varying T2* values between measurements. In this work,
B0 maps are used to correct the T2* images for more
accurate quantification.
