Unlabelled:
The aim of the study was to describe MR imaging findings in patients after acute carbon monoxide poisoning.
Material And Method:
In the period of 7 months (from October 2011 to April in 2012), 72 patients were hospitalized at the Center of Clinical Toxicology after acute carbon monoxide poisoning. In all patients the level of carboxyhemoglobin (COHb) was determined. Brain MR examination was performed in 14 patients of this group due to persistent neurological symptoms.
Results:
In 72 patients the mean value of COHb was 21.52%. In 14 patients with persistent neurological symptoms mean value of COHb was 26.14%. In 14 patients who underwent MRI of the brain, in 4 there was no MR change and their COHb average value was 20.45%. In the remaining 10 patients MR brain abnormalities were diagnosed, including changes of basal ganglia, white matter or cortex, and their COHb average value was 26.56%.
Conclusions:
In patients with persistent neurological symptoms after acute carbon monoxide poisoning are changes in brain MRI. These changes correlate with the concentration of COHb. MRI seems to be the method of choice for imaging the brain in patients after acute carbon monoxide poisoning.
