UNLABELLED Our purpose was to evaluate the ability of FDG PET to differentiate recurrent
tumor from posttherapy radiation necrosis. METHODS MR images, PET scans, and medical …

PURPOSE: To quantify the relative contributions of spin density and T2 effects (“shine
through”) on diffusion-weighted (DW) magnetic resonance (MR) images of acute and subacute …

The objective of this study was to determine the time course of signal intensity changes on
diffusion-weighted MR images after cerebral infarction. Echoplanar diffusion-weighted MR …

Imaging plays a crucial role in the diagnosis and management of low- and intermediate-grade
gliomas. In this article, the traditional role of imaging studies in glioma patients and the …

BACKGROUND AND PURPOSE: Echo-planar diffusion-weighted and fluid-attenuated
inversion-recovery (FLAIR) imaging have both proved valuable for detecting acute ischemic …

BACKGROUND AND PURPOSE: Single-voxel MR spectroscopy is a widely used tool for
evaluating brain tumors. Although extensive data are available on the MR spectral appearance …

Imaging continues to play an important role in the evaluation and management of patients
with primary and metastatic brain tumors. This article provides a generalized framework for …

We evaluated the relative accuracy of calculating apparent diffusion coefficients (ADCs) of
intracranial tissues using a two-point versus a six-point regression technique. Echo planar …

FUNCTIONAL magnetic resonance imaging (fMRI) and transcranial magnetic stimulation (TMS)
are noninvasive techniques recently used to investigate cortical motor physiology. …

Primary objectives: To evaluate (1) the sensitivity of magnetic resonance imaging (MRI) T2*
weighted gradient echo (GE) vs T2 weighted spin echo (SE) technology for lesion detection …
