Four patients who had carbon monoxide intoxication were examined by brain magnetic resonance imaging (MRI) and computed tomography (CT). Three were unconscious in the acute stage of intoxication. On regaining consciousness. neuropsychological symptoms and signs remained. In these patients, T2‐weighted MRI demonstrated hyperintensity lesions in the cerebral cortex, most prominent in the watershed zone. The fourth patient had only memory disturbance and was not unconscious during the acute intoxication. The T1‐weighted MRI showed hyperintensity in the bilateral pallidal regions. MRI demonstrated lesions more clearly than did CT.
