[Magnetic resonance imaging in the study of brain changes due to carbon monoxide poisoning].

Five cases of carbon monoxide intoxication were studied with MR imaging. The main MR findings were discussed and compared with CT results. MR imaging demonstrated SNC lesions sooner and better than CT--its images corresponding to the anatomic-pathological patterns described in literature. However, severe MR limitations--i.e., the very long execution time and the difficult monitoring of the patients--prevent this methodology from being more extensively employed in this kind of pathology.
