Introduction: Non-invasive quantification of liver fat by Gradient echo (GRE) Technique is an interesting issue in quantitative MRI. Despite the numerous advantages of this technique, fat measurement maybe biased by confounding and effects. The aim of this study was to evaluate the GRE pulse sequences with different   and  weighting for liver fat quantification in patients with...

A 59-year-old man with a family history of cerebral cavernous malformations (CCM) presented with focal seizures. T2*-weighted gradient echo (GRE) images showed multiple lesions consistent with cavernous malformations (figure 1). Susceptibility-weighted images (SWI) detected nearly triple the number of lesions than were seen with the GRE sequence (figure 2). SWI is a relatively new MRI technique...

Given a system design (SD), a key task is to optimize this design to reduce the probability of catastrophic failures. We consider the task of redesigning an SD to minimize the probability of particular faults by introducing components selected from a component library. We have implemented a General Redesign Engine (GRE), which uses model-based reasoning techniques and Boolean functional synthes...

background: the purpose of this study is to demonstrate the advantages of gradient echo (gre) sequences in the detection and characterization of cerebral venous sinus thrombosis compared to conventional magnetic resonance sequences. methods: a total of 17 patients with cerebral venous thrombosis (cvt) were evaluated using different magnetic resonance imaging (mri) sequences. the mri sequences i...

OBJECTIVES The goal of this work was to reduce the scan time of contrast-enhanced whole-heart coronary magnetic resonance angiography (MRA) by using a gradient echo interleaved echo planar imaging (GRE-EPI) sequence at 3 T field strength. MATERIALS AND METHODS A GRE-EPI sequence was optimized to acquire contrast-enhanced whole-heart coronary MRA at 3 T. First-order phase correction was used f...

BACKGROUND Galla Rhois has been considered to have medicinal properties against diarrhea, excessive sweating, bleeding, and chronic cough in Asian countries. Gallotannins, which are Galla Rhois-derived tannins, have been reported to possess biological and pharmacological activities, especially anticancer activity. In this study, we evaluated the effect of steaming at a temperature over 120 °C o...

PURPOSE To implement in-phase and out-of-phase (IP/OP) techniques with Magnetization-Prepared Gradient Recalled Echo (MP-GRE) and to evaluate the feasibility and diagnostic image quality among pre and post-optimized MP-GRE sequences, including patients unable to cooperate with breath-hold requirements. MATERIALS AND METHODS Institutional review board approval with waiver of informed consent w...

The task of generating referring expressions, an important subtask of Natural Language Generation is to generate phrases that uniquely identify domain entities. Until recently, many GRE algorithms were developed using only simple and essentially home-made formalisms. Following the fast development of ontology-based systems, reinterpretations of GRE in terms of description logic have been studie...
