As part of the Carotid Occlusion Surgery Study (COSS), patients with chronic cervical carotid artery occlusive disease are selected for extracranial-intracranial bypass surgery based on the results of 15O2/H215O PET imaging. The purpose of this study was to compare the results of Perfusion-CT (PCT) with those of 15O2/H215O PET in a subset of COSS patients.
