MRI image characteristics of cerebral infarction.
Note: Fig 5A, 5C–5E referred to the MRI images of lesion, cerebral artery, degree of vessel stenosis, and vessel branches, respectively; and 5B showed a DWI image of lesion.

Comparison on ADC values different brain parts in the affected and normal side.
A–J referred to the semi-oval center, the posterior horn of the lateral ventricle, the forelimb of the internal capsule, knee of internal capsule, the hind limbs of internal capsule, lenticular nucleus, the brain stem, the infarct central area, the marginal area of infarct focus, and the normal area around the focus, respectively. (** indicated the difference was huge in contrast to the affected side (P < 0.01)).
