Brain MRI. (A and B) Serial FLAIR MRI shows the high signal intensity in the territory of the right anterior cerebral artery, which indicates recent cerebral infarction. MRI = magnetic resonance imaging.

The results of the brain magnetic resonance imaging study disclosed an infarction in the region of the right anterior cerebral artery (Fig. 1).
Regional perfusion SPECT before and after intravascular laser irradiation. The 2 SPECT images show the regional perfusion. The white to red area indicated better perfusion than the blue and green area. (A) This regional perfusion SPECT (conducted on poststroke day 14) shows that the infarction region (indicated by red arrow) covers the territory of the anterior cerebral artery on the right hemisphere and decreased perfusion on the left cerebellar hemisphere (indicated by red arrow head). (B) The second regional perfusion SPECT (conducted on poststroke day 63) still showed hypoperfusion in the right cerebral hemisphere (indicated by white arrow), but more blood flow in the left cerebellar hemisphere (indicated by white arrow head). SPECT = single-photon emission computed tomography.

The brain regional perfusion was imaged by single-photon emission computed tomography (SPECT) (Fig. 2A) 2 weeks after the stroke and disclosed CCD on the left side. CCD had greatly improved (Fig. 2B). Comparing the 2 regional perfusion SPECT data, we found that the blood perfusion in the right cerebellar hemisphere showed greater resemblance to the left cerebellar hemisphere in the second SPECT after ILIB.
