Abstract
The authors carried out a Matas test with a regional cerebral blood flow (rCBF) study using H2(15)O positron emission tomography (PET) for three cases of large internal carotid artery aneurysms. There is a likely correlation between the cerebral blood flow (CBF) reduction rate obtained by PET, and the mean stump pressure available from a conventional balloon occlusion test. The advantages of this noninvasive and quantitative method are presented in comparison with other methods.
