The current diagnosis of MND is based on results of the clinical examination and neurophysiologic studies. The length of time of referral to a neuromuscular neurologist and the lack of validated diagnostic criteria can delay diagnosis. Although the role of imaging is currently most useful in excluding other conditions, several attempts to incorporate neuroimaging in the diagnosis of the disease and assessment of progression have shown promising results %K corticospinal tract hyperintensities %K CST hyperintensities %K MND %K motor neuron disease %K possible MND %K possible motor neuron disease %K quantitative and functional MRI %K ribbon like hypointensities %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6380476/
