Brain perfusion imaging in amyotrophic lateral sclerosis: Extent of cortical changes according to the severity and topography of motor impairment

In amyotrophic lateral sclerosis (ALS), attempts have been made to correlate the extent of cortical lesions with the intensity of motor dysfunction in ALS patients. Our aim was to compare the cerebral perfusion as measured by SPECT with the topography and severity of motor impairment as measured by...
