Regional cerebral blood flow in patients with carbon monoxide intoxication

摘要

Early detection of regional cerebral anomalies in acute carbon monoxide (CO) poisoning by 99mTc-hexamethylprophylene amine oxime (HMPAO) brain single photon emission computed tomography (SPECT) imaging has been reported previously. However, SPECT findings varied in these studies because of their small population sizes. In this study, we included 96 patients with acute CO intoxication and analyzed the regional perfusion changes in these patients by means of HMPAO brain SPECT.
