Effects of intravascular photobiomodulation on motor deficits and brain perfusion images in intractable myasthenia gravis: A case report

Figure 3 Regional perfusion brain single-photon emission computed tomography before and after therapeutic intravascular laser irradiation of blood intervention (sagittal view). The white to red and green to blue areas indicate high and low perfusion, respectively. A:The first single-photon emission computed tomography (SPECT) (before ILIB intervention) shows perfusion deficits in the frontal lobe (white arrows); B: The second SPECT [after the third course of intravascular laser irradiation of blood (ILIB) intervention] shows more blood flow in the frontal lobe (white arrows). ILIB: Intravascular laser irradiation of blood.
