Answer

MRI is more accurate than CT scans for detection of focal lesions and white matter demyelination and is often used for follow-up care. [32]  The progression from conventional MRI to diffusion-weighted imaging (DWI) and then diffusion tensor imaging (DTI) has enabled increasingly sensive evaluation of damage from CO poisoning. DTI can visualize progressive pathologic changes in the early stage of CO toxicity, allowing prediction of chronic conditions. [8]
