Amyotrophic lateral sclerosis: T2 shortening in motor cortex at MR imaging.


PURPOSE To determine whether decreased signal intensity of the motor cortex (T2 shortening) at magnetic resonance (MR) imaging is a useful finding for supporting the diagnosis of amyotrophic lateral sclerosis (ALS). MATERIALS AND METHODS High-field-strength (1.5-T) MR images of 15 patients (seven men and eight women, aged 28-80 years) and 49… (More)
