This research examined the benefits of interpreting physiological arousal as a challenge response on practice and actual Graduate Record Examination (GRE) scores. Participants who were preparing to take the GRE reported to the laboratory for a practice GRE study. Participants assigned to a reappraisal condition were told arousal improves performance, whereas control participants were not given ...

This specification defines a new mobility option for allowing the mobile access gateway and the local mobility anchor to negotiate Generic Routing Encapsulation (GRE) encapsulation mode and exchange the downlink and uplink GRE keys that are used for marking the downlink and uplink traffic that belong to a specific mobility session. In addition, the same mobility option can be used to negotiate ...

BACKGROUND AND PURPOSE In contrast to platelet-rich white thrombi, red thrombi in the heart are rich in fibrin and trapped erythrocytes. The magnetic susceptibility effect of deoxygenated hemoglobin in red thrombi may result in hypointense signals on T2*-weighted gradient echo imaging (GRE). We tested the hypothesis that a GRE susceptibility vessel sign (SVS) is specific for cardioembolic strok...

Glioma-related edema (GRE) is a significant contributor to morbidity and mortality from glioma. GRE is a complicated process involving not only peritumoral edema but also the water content of the tumor body. In terms of etiology, this condition derives from both GRE in the untreated state and GRE secondary to clinical intervention, and different cell types contribute to distinct components of G...

Nineteen consecutive patients with spinal intramedullary lesions were studied on a 1.5-T system to compare the quality of T2-weighted spin-echo and gradient-recalled-echo (GRE) pulse sequences. Direct comparisons were made in the sagittal and/or axial planes. Twenty-four studies were performed in the 19 patients. The gradient echoes were usually performed at 300/14 (TR/TE) with a flip angle of ...

Introduction: 3D gradient echo (GRE) sequence is commonly used for T1-weighted MR imaging of liver. Conventional 3D GRE sequences utilize either one of centric-linear, radial or linear ordering of k-space with a fat suppression technique and partial scan technique along a slice direction. We introduce a enhanced 3D-GRE sequence, which adopted a linear ordering with half scan along both slice an...

In general, gradient echo (GRE) is used for the echo acquisition of two-dimensional time-of-flight (2D-TOF). It takes time to the image acquisition by 2D-TOF. Then, we designed the use of GRE-echo planar imaging (EPI) to the echo collections of 2D-TOF. We compared two pulse sequences using the following: contrast, signal to noise ratio, the distortions, and magnetic resonance angiography (MRA) ...

PURPOSE To evaluate high-resolution MRI of the triangular fibrocartilage complex (TFCC) at 3T using a surface coil (SC) or volume coil (VC). MATERIALS AND METHODS MRI was obtained from nine volunteers in the supine position with a 3-inch SC and in prone position with a transmit-receiver wrist VC at 3 T. Coronal two-dimensional-gradient echo (2D-GRE) images (TR/TE/FA = 500 msec/15 msec/40 degr...
