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

Figure 3 A 67-year-old male patient was admitted to the hospital due to dizziness, vomiting, and limb dysfunction for 12 h. Magnetic resonance imaging examination was performed within 4 h after admission, and the patient was diagnosed with acute cerebral infarction in the left frontal lobe. A: The diffusion-weighted imaging image and the focal area of cerebral infarction showing high signal performance; B: The color map of cerebral perfusion, showing significant hypoperfusion in the infarct lesion area; C: T2-weighted imaging, with the infarct area indicated by the white arrow showing high signal intensity (Arrow).
