Abstract:
To study degeneration in the central nervous system in amyotrophic lateral sclerosis (ALS), we studied four patients using single photon emission tomography (SPECT) and magnetic resonance imaging (MRI). MRI demonstrated high intensity along the pyramidal tract on T2-weighted images in two. SPECT demonstrated reduced isotope uptake restricted to the motor area. While the cause of degeneration of the cortical neurons in the motor area is unknown, SPECT is useful for detecting the degeneration in patients with ALS.
