BACKGROUND AND PURPOSE: The different sensitivities to vessel size of gradient-echo
echo-planar imaging (GE-EPI) and spin-echo EPI (SE-EPI) might indicate the relative …

Objective To determine the usefulness of perfusion MR imaging in assessing the histologic
grade of cerebral gliomas. Materials and Methods In order to determine relative cerebral …

BACKGROUND AND PURPOSE: No widespread clinical method provides specific
information about the angiogenic characteristics of gliomas. We characterized blood volume …

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 …

A significant number of nonenhancing (NE) gliomas are reported to be malignant. The
purpose of this study was to compare the value of advanced MR imaging techniques …

Neovascularization is a common phenomenon in gliomas. MR imaging cerebral blood
volume (CBV) mapping utilizes ultrafast echo-planar imaging and simultaneous use of …

BACKGROUND AND PURPOSE: After bolus injection, gadopentetate dimeglumine causes
a T2* rate change in permeable tissue that is contaminated by the T1 shortening effect due …

AIM: Relative cerebral blood volume (rCBV) is a commonly used perfusion magnetic
resonance imaging (MRI) technique for the evaluation of tumour grade. Relative cerebral …

Our purpose was to evaluate the relationships between the ratio of maximum relative
cerebral blood volume (rCBV)(rCBV ratio= rCBV [tumor]/rCBV [contralateral white matter]) …

PURPOSE: To evaluate the role of T2*-weighted echo-planar perfusion imaging by using a
first-pass gadopentetate dimeglumine technique to determine the association of magnetic …
