Two consecutive measurements of resting CBF were carried out in normal volunteers (n=
25) using H215O positron emission tomography. Absolute whole-brain blood flow (WBBF; …

The sensitivity and reproducibility of rapid measurements of regional cerebral flow (rCBF)
using a bolus injection of H 2 15 O and dynamic positron emission tomography (PET) were …

207 Objectives Arterial spin labeling (ASL) is a magnetic resonance (MR) method for
measuring cerebral blood flow (CBF) in vivo, and it has great potential for clinical …

Assessment of quantitative cerebral blood flow on a conventional fast CT machine without
the use of specialized equipment may be valuable in the investigation of acute stroke and …

Objective Arterial input function represents the delivery of intravascular tracer to the brain.
The optimal setting of this function is essential for measuring regional cerebral blood flow …

A noninvasive method to estimate input function directly from H 2 15 O brain PET data for
measurement of cerebral blood flow (CBF) was proposed in this study. The image derived …

Objective Cerebral blood flow (CBF) estimation with C 15 O 2 PET usually assumes a single
tissue compartment model and a fixed brain–blood partition coefficient of water. However …

Objective The brain uptake ratio (BUR) method for the 99m Tc-ECD SPECT, a non-invasive
measurement method of rCBF, has been used in clinical practice in Japan, because it is …

We previously developed an alternative method for estimating the brain perfusion index
(BPI) using technetium-99m compounds and spectral analysis (SA) for quantification of …

The limited spatial resolution of SPECT causes a partial volume effect (PVE) and can lead to
the significant underestimation of regional tracer concentration in the small structures …
