To evaluate the appropriate model for calculating regional cerebral blood flow (rCBF) with
PET and H215O, the values obtained from 1-and 2-compartment analyses were compared …

Purpose It is generally assumed that vascular tracer activity is negligible in the quantification
of regional cerebral blood flow (rCBF) with H 2 15 O and positron emission tomography …

The quantitative determination of regional cerebral blood flow (rCBF) is important in certain
clinical and research applications. The disadvantage of most quantitative methods using H 2 …

Purpose A noninvasive image derived input function (IDIF) method was applied to estimate
arterial input function from brain H 2 15 O-PET/MRI images for the measurement of cerebral …

This work describes the determination of CBF in eight normal human subjects with positron
emission tomographic (PET) imaging using the continuous intravenous infusion of H215O. A …

One of the most limiting factors for the accurate quantification of physiologic parameters with
positron emission tomography (PET) is the partial volume effect (PVE). To assess the …

A system for CBF measurement using an H215O autoradiographic method and positron
emission tomography (PET) has been designed and installed as a clinical tool. Following an …

In quantitative functional neuroimaging with positron emission tomography (PET) and
magnetic resonance imaging (MRI), cerebral blood volume (CBV) and its three components …

Limited spatial resolution of positron emission tomography (PET) can cause significant
underestimation in the observed regional radioactivity concentration (so-called partial …

In 20 patients with unilateral cerebrovascular disease, regional cerebral blood flow (rCBF)
was measured by F-18-fluoromethane inhalation and positron emission tomography (PET) …
