From: Intravascular laser irradiation of blood as novel migraine treatment: an observational study
Regional cerebral blood flow imaging through single-photon emission computed tomography (rCBF-SPECT) scan of cerebral blood flow. A Rehabilitation group and B ILIB group. Preintervention and postintervention rCBF-SPECT did not differ significantly in the rehabilitation group, but rCBF was significantly higher in the patients with migraine after ILIB treatment. C Left panel presents the mean (error bars: standard deviation) rCBF differences between treatment groups for various brain regions. Right panel presents preintervention and postintervention rCBF differences in the ILIB group. D Between-group comparison of changes in rCBF in various brain regions. E Comparison of changes in region-specific rCBF between rehabilitation and ILIB groups. A significant difference was observed in rCBF before and after ILIB treatment. ILIB, intravascular laser irradiation of blood; Rehab, rehabilitation; ROI, region of interest.
