Using MRI for the assessment of paraoxon-induced brain damage and efficacy of antidotal treatment.

Organophosphate intoxication induces neural toxicity as demonstrated in histological analysis of poisoned animals. Diffusion-weighted magnetic resonance imaging (DWMRI) enables early noninvasive characterization of biological tissues based on their water diffusion characteristics. Our objectives were to study the application of MRI for assessment of paraoxon-induced brain damage and the efficacy of antidotal treatments.
