BACKGROUND AND PURPOSE: For patients with high-grade gliomas, the appearance of a
new, enhancing lesion after surgery and chemoradiation represents a diagnostic dilemma …

Rationale and Objectives Magnetic resonance (MR) perfusion techniques and MR
spectroscopy (MRS) provide specific physiological information that may allow distinction …

RATIONALE AND OBJECTIVES: Distinguishing recurrent glial tumor from radiation necrosis
can be challenging. The purpose of this pilot study was to preliminarily compare …

MR perfusion imaging is important in the clinical evaluation of primary brain tumors,
particularly in differentiating between true progression and treatment-induced change. The …

Background: Gliomas constitute over 90% of primary brain tumors. Accurate identification of
glioma recurrence and treatment effects is important, as it can help determine whether to …

OBJECTIVE. The purpose of this article is to address radiation necrosis, pseudoprogression,
and pseudoresponse relative to high-grade gliomas and evaluate the role of conventional …

BACKGROUND AND PURPOSE: The purpose of this study was to determine whether
qualitative and quantitative measures obtained with pulsed arterial spin-labeling (PASL) and …

Several studies evaluated the predictive value of dynamic susceptibility contrast enhanced
(DSC) imaging and arterial spin labeling (ASL) with regard to histological grade. Yet still less …

Arterial spin labeling (ASL) magnetic resonance (MR) perfusion imaging has been proposed
as an effective method to measure brain tumor perfusion. The aim of the present study was …

Purpose Predicting malignant progression of grade II gliomas would allow for earlier
initiation of treatment. The hypothesis for this single-centre, case–control study was that the …
