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

Figure 4 Regional perfusion brain single-photon emission computed tomography before and after therapeutic intravascular laser irradiation of blood intervention (coronal view). The white to red and green to blue areas indicate high and low perfusion, respectively. A: The first SPECT (before ILIB intervention) shows perfusion deficits at the anterior cingulate gyri (white arrows); B: The second SPECT (after the third course of ILIB intervention) shows high activity in the anterior cingulate gyri (black arrows). ILIB: Intravascular laser irradiation of blood; SPECT: Single-photon emission computed tomography.
