What Researchers Did
Researchers performed Tc-HMPAO isotope brain scans on three patients who received hyperbaric oxygen treatment following carbon monoxide poisoning.
What They Found
The study found that cerebral perfusion imaging provided an index of the initial severity of brain damage in these three patients. This index correlated with the patients' outcomes following carbon monoxide poisoning.
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada or by Canadian researchers.
Study Limitations
A significant limitation of this study is its very small sample size of only three patients.
