Diffusion MRI in Acute Carbon Monoxide Poisoning

Acute Carbon Monoxide Poisoning in a Poisoning Referral Center

Bachground: Acute carbon monoxide poisoning (COP) is a common problem that occurs more frequently during winter and leads to serious complications. In our Poisoning Referral Center, the incidence and complications of acute COP has not been evaluated previously. Therefore we designed a study to evaluate its significance in our center. Methods & Materials: 111 cases of acute COP admitted duri...

Structural Findings in the Brain MRI of Patients with Acute Carbon Monoxide Poisoning

Background: Carbon monoxide (CO) poisoning may lead to hypoxic/anoxic injury and eventually ischemic encephalopathy. Magnetic resonance imaging (MRI) has a well-recognized role in assessment of the severity of brain damage caused by CO poisoning. In this study, we aimed to present and analyze the structural abnormalities in the brain MRI and especially in diffusion weighted MRI (DWI) images in ...

Acute carbon monoxide poisoning: diffusion MR imaging findings.

During the acute stage of carbon monoxide poisoning, diffusion MR images obtained at b=1000 s/mm2 revealed high signal intensity lesions in the white matter, consistent with restricted diffusion. Low apparent diffusion coefficient values (0.18-0.34 x 10(-3) mm2/s) were noted in the affected white matter regions. Follow-up MR imaging performed 16 days later revealed disappearance of white matter...

Pulmonary edema in acute carbon monoxide poisoning.

The chest radiograms and the arterial Po2 values were studied in 61 patients suffering from severe acute CO poisoning. 22 patients (36.1~ showed abnormalities on chest film taken at the time of admission. The radiologic pulmonary abnormalities were classified into three patterns: 1. ground glass density, 2. interstitial edema, and 3. intraalveolar edema. Particular emphasis was placed on the di...
