Table 3.

Top 3 texture descriptors and their PCA-scores listed for T1-w, T2-w, and FLAIR MRI protocols for MET patients. HoG features were consistently identified as best performing features across all 3 MRI protocols for distinguishing RN and rBT for MET patients.

MRI protocol	Texture descriptor	π _ϕ,β
Gd-C T1-w MRI	HoG (0-35)	1.98
	Laws (E5L5)	1.78
	Gabor (Θ = 135, ʌ = 32)	1.51

T2-w MRI	HoG (108-143)	1.71
	Sum Entropy	1.49
	Sum Variance	1.39

FLAIR MRI	HoG (72-107)	1.91
	Laws (E5L5)	1.88
	Laws (L5E5)	1.63
