a) Average values for mean, axial and radial diffusivity (MD, AD, and RD) and
kurtosis (MK, AK, and RK) and fractional anisotropy (FA) in the solid lesion,
surrounding perilesional white matter (pWM) and contralateral normal appearing
white matter (cNAWM) in 19 patients with low-grade gliomas. Mean, axial and
radial diffusivity have units 10−3 mm2/sec; mean,
axial and radial kurtosis and fractional anisotropy are dimensionless. The
significance of paired differences are shown by * denoting False
Discovery Rate (FDR) corrected p <0.001. b) Effect size calculated using
Cohen’s d for paired differences.
