Table 1 Evaluating Peak Systolic Criteria by follow-up magnetic resonance imaging/magnetic resonance angiogram

	MRI/MRA
		Condition/abnormal	Normal
Peak systolic criteria	Conditional/abnormal	16	4
Peak systolic criteria	Normal	6	17

The sensitivity was 73% [16/(16 + 6)] and specificity was 81% [17/(4 + 17)]. MRI: Magnetic resonance imaging; MRA: Magnetic resonance angiogram.

Table 2 Evaluating mean velocity criteria by follow-up magnetic resonance imaging/magnetic resonance angiogram

	MRI/MRA
		Condition/abnormal	Normal
Mean velocity criteria	Conditional/abnormal	9	0
Mean velocity criteria	Normal	13	21

The sensitivity was 41% [9/(9 + 9 + 13)] and the specificity was 100% [21/(21 + 0)]. MRI: Magnetic resonance imaging; MRA: Magnetic resonance angiogram.
