Objective To assess the diagnostic value of MRI in acute carbon monoxide poisoning. Methods The clinical and MRI data of 59 patients with acute carbon monoxide poisoning were analysed. Results The MRI showed the necroses and degeneration of flobus pallidus, edema of bilateral cerebral white matter with prolonged T1 and T2 signals within periventricular regions and with subsequent cerebral atrophy and hippocampus changes. Conclusion The diagnosis of acute carbon monoxide poisoning mainly depends on case history, clinical features and neuroradiological presence. MRI is very valuable in the diagnosis and the prognosis.
