BACKGROUND AND PURPOSE: Measurement of perfusion parameters is typically done
using an intravenous injection of contrast medium. This purpose of this study was to …

BACKGROUND AND PURPOSE: Assessment of perfusion parameters is important in the
selection of patients who are most likely to benefit from revascularization after an acute …

BACKGROUND AND PURPOSE: CBV is a key parameter in distinguishing penumbra from
ischemic core. The purpose of this study was to compare CBV measurements acquired with …

BACKGROUND AND PURPOSE: Cerebral blood volume (CBV) is an important parameter in
estimating the viability of brain tissue following an ischemic event. We tested the hypothesis …

BACKGROUND AND PURPOSE: Previous studies have shown the feasibility of assessing
qualitative CBV measurements in the angiography suite by using FPD-CBCT systems. We …

BACKGROUND AND PURPOSE: Parenchymal blood volume measurement by C-arm CT
facilitates in-room peritherapeutic perfusion evaluation. However, the radiation dose …

The cerebral blood volume (CBV) has been measured by transverse axial tomography. The
attenuation coefficient of 100 “pixels” located in a well determined region was measured …

OBJECTIVE: This study aimed to determine a contrast medium injection rate that ensures
both accuracy for data and safety for operation by comparing hemodynamic parameters of …

BACKGROUND AND PURPOSE: In CTP, an arterial input function is used for cerebral blood
volume measurement. AIFs are often influenced by partial volume effects resulting in …

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