About

Adult patients who are diagnosed with an acute supratentorial ischemic stroke within 48 hrs of onset will be enrolled into the study. Participants will undergo both a CT Scan and PET scan within 7 days of onset. Participants will have the option to undergo a second PET scan with fluorodeoxyglucose (FDG).

Full description

Patients older than 18 years of age diagnosed with an acute supratentorial ischemic stroke within 48 hrs of symptom onset will be prospectively enrolled. Research imaging will be obtained before 7 days after symptom onset. The patient will receive the standardized treatment protocol at the hospital. Informed consent will be obtained from each patient or a substitute decision maker for each individual imaging study (CTP, Rb PET, and FDG PET). The patient will be given the option of undergoing the CTP imaging with the Rb PET only or both the Rb PET and FDG PET components.
