PURPOSE: The purpose of this study was to examine the relationship between contrast
transfer coefficient [Ktrans] and grade in gliomas. MATERIAL AND METHODS: Median …

INTRODUCTION: Noninvasive measurements of cerebral blood volume (CBV) and contrast
transfer coefficient (Ktrans) have potential benefits in the diagnosis and therapeutic …

Purpose: To evaluate the roles of dynamic contrast‐enhanced magnetic resonance imaging
(DCE‐MRI) and optimum tracer kinetic parameters in the noninvasive grading of the glial …

BACKGROUND AND PURPOSE: Relative cerebral blood volume (rCBV) estimates for high-
grade gliomas computed with dynamic susceptibility contrast MR imaging are artificially …

OBJECTIVE. Relative cerebral blood flow has rarely been studied as part of the preoperative
assessment of tumor grade, although relative cerebral blood volume is known to be useful …

BACKGROUND AND PURPOSE: The prognostic value of dynamic contrast-enhanced MR
imaging–derived plasma volume obtained in tumor and the contrast transfer coefficient has …

OBJECTIVE. The purpose of this study was to correlate the degree of contrast enhancement
on dynamic contrast-enhanced T1-weighted MRI and the relative cerebral blood volume …

BACKGROUND AND PURPOSE: Estimates of blood volume and volume transfer constant
are parameters commonly used to characterize hemodynamic properties of brain lesions …

BACKGROUND AND PURPOSE: Glioma angiogenesis and its different hemodynamic
features, which can be evaluated by using perfusion CT (PCT) imaging of the brain, have …

BACKGROUND AND PURPOSE: Abnormalities in the recirculation phase of the passage of
a contrast agent bolus have been identified in tumors and have been suggested to represent …
