Recent positive trials have thrust acute cerebral perfusion imaging into the routine
evaluation of acute ischemic stroke. Updated guidelines state that in patients with anterior …

In 1979, just 8 years after Godfrey Hounsfield's introduction of CT, Leon Axel first proposed a
method for determining tissue perfusion from dynamic contrast enhanced CT data [1]. Due to …

Knowledge of regional cerebral hemodynamics has widespread application for both
physiological research and clinical assessment because of the well-established interrelation …

Abstract Knowledge of regional hemodynamics has widespread application for both
physiological research and clinical assessment. Here we review the use of MR contrast …

Background and Purpose—Different definitions have been proposed to define the ischemic
penumbra from perfusion-CT (PCT) data, based on parameters and thresholds tested only in …

Objective To systematically evaluate the accuracy of noncontrast computed tomography

With the introduction of molecularly targeted chemotherapeutics, there is an increasing need
for defining new response criteria for therapeutic success because use of morphologic …

A method for quantifying tissue perfusion by dynamic computed tomography (CT) is
described. By applying a nuclear medicine data processing technique to time-density data …

The myocardial perfusion reserve, defined as the ratio of hyperemic and basal myocardial
blood flow, is a useful indicator of the functional significance of a coronary artery lesion …

The purpose of this study was to determine the prognostic accuracy of perfusion computed
tomography (CT), performed at the time of emergency room admission, in acute stroke …
