Description

Highlights: • The hypointense iron-induced SWI signal of the DN is not observed in AOA patients. • The absence of the DN hypointense signal is a new sign of outstanding specific value. • DN signal on FLAIR and SWI could be considered as a diagnostic criterion of AOA. - Abstract: Purpose: Evaluate the specificity and sensitivity of disappearance of susceptibility weighted imaging (SWI) dentate nuclei (DN) hypointensity in oculomotor apraxia patients (AOA).
