Perfusion CT studies of regional cerebral blood flow (rCBF), involving sequential acquisition
of cerebral CT sections during IV contrast material administration, have classically been …

BACKGROUND AND PURPOSE: Knowledge of cerebral blood flow (CBF) alterations in
cases of acute stroke could be valuable in the early management of these cases. Among …

Viability of the cerebral parenchyma is dependent on cerebral blood flow (CBF), which is
usually kept in a very narrow range due to efficient autoregulation processes and can be …

The influence of the frequency of computed tomography (CT) image acquistion on the
diagnostic quality of dynamic perfusion CT (PCT) studies of the brain was investigated. Eight …

PURPOSE: To validate a dynamic single-section computed tomographic (CT) method to
measure cerebral blood volume (CBV) and cerebral blood flow (CBF) by using a noncarotid …

The ability to demonstrate regions of abnormal cerebral blood flow in the setting of acute
stroke is of diagnostic and prognostic importance. It may also influence therapeutic …

BACKGROUND AND PURPOSE: Blood vessels are usually conspicuous on dynamic CT
perfusion images. The presence of large vessels may lead to overestimation of the …

Purpose: To preliminarily evaluate the feasibility and potential diagnostic utility of whole-
brain perfusion computed tomography (CT) performed with a prototype 256–detector row CT …

PURPOSE: To determine the value of perfusion computed tomography (CT) in a clinical
study of patients with stroke and compare the results with single photon emission CT …

Perfusion computed tomography (PCT) is an imaging technique that allows rapid,
noninvasive, quantitative evaluation of cerebral perfusion by generating maps of cerebral …
