Arterial spin labeling in the grading of brain gliomas: could it help?

Egyptian Journal of Radiology and Nuclear Medicine

Table 5 Agreement (sensitivity, specificity) for ASL relative CBF (WM), DSC relative CBF (WM), and DSC relative CBV (WM) to differentiate high (n = 21) from low (n = 14) grade gliomas

	AUC	p	95% C.I	Cutoff	Sensitivity	Specificity	PPV	NPV	Accuracy
ASL relative CBF (WM)	0.925^*	< 0.001^*	0.84–1.01	> 2.08	80.95	85.71	89.5	75.0	82.86
DSC relative CBF (WM)	1.000^*	< 0.001^*	1.00–1.00	> 0.9	100.0	100.0	100.0	100.0	100.0
DSC relative CBV (WM)	1.000^*	< 0.001^*	1.00–1.00	> 1.1	100.0	100.0	100.0	100.0	100.0
