Prediction results of the ASL-nCBF classification model for low- and high-grade gliomas.

Test data # (n = 4)	#1 (Diffuse astrocytoma, grade II)	#2 (Anaplastic oligodendroglioma, grade III)	#3 (Glioblastoma, grade IV)	#4 (Glioblastoma, grade IV)

^aCut-off value: 0.517; ^bp: probability of a patient with high-grade glioma (0 < p < 1); ASL-nCBF, arterial spin labeling normalized cerebral blood flow; LGG, low-grade glioma; HGG, high-grade glioma.
