摘要: AbstractAssessment of quantitative cerebral blood flow on a conventional fast CT machine without the use specialized equipment may be valuable in investigation acute stroke and head injury. We aimed to compare single slice perfusion sequence with H2150 positron emission tomography using sagittal sinus as an input function, method that avoids unnecessary orbital irradiation. Eight patients were studied, two gliomas, six arteriovenous malformations. The dynamic was performed by acquiring same 7 0 mm 10 times over 30 sec during 50 ml bolus intravenous contrast medium given at rate 7.5 sec~^ power injector. studies completed complication. Co-registration sub-optimal one patient. Overall correlation between methodologies encouraging average r2 value of0.524 for individual analyses. When high malformations excluded...
