Three-dimensional arterial spin labeling and diffusion kurtosis imaging in evaluating perfusion and infarct area size in acute cerebral ischemia

Table 2 Comparison of cerebral blood flow values between the lesion area and control area under different parameters of different delay time after labeling (mean ± SD, mL/100 g/min)

Control area	84	34.51 ± 7.03	37.58 ± 7.76
t value		-11.929	-24.839
P value		0.000	0.000
