Introduction Accurate segmentation and appropriate visualization of the arteries and veins in the brain improve the detection and characterization of vascular abnormality such as cerebral aneurysm, arteriovenous malformation and tumor vascularity. Traditional 2D projection display of vascular images such as minimum-intensity projection (minIP) of veins in MRV offers limited visualization of com...

A 20-year-old woman was admitted to a Gynecology Hospital in her 6(th) month of pregnancy for high blood pressure and tonic-clonic seizure. Primary diagnosis was eclampsia, and for that reason she underwent cesarean section. She also had headache on frontal and parietal areas without nausea or vomiting. There was not a focal neurological sign. Rheumatology consultation was requested. Systemic l...

The The kinematic interrelationships between the lower limbs, pelvis, trunk, and racquet in the performance of the high velocity tennis serve were investigated for 10 participants using a 12 camera opto-reflective Vicon MX system, operating at 250Hz. The average absolute peak racquet centre velocity was 34.0m∙s-1, which is comparable to previous studies using high performance players. Peak vert...

We build a sharp approximation of the whole distribution sum iid heavy-tailed random vectors, combining mean and extreme behaviors. It extends so-called ’normex’ approach from univariate to multivariate framework. propose two possible multinormex distributions, named d-Normex MRV-Normex. Both rely on Gaussian for describing behavior, via CLT, while difference between versions comes using exact ...

Introduction: So far, the standard technique for magnetic resonance venography (MRV) is the 2D time-of-flight method. However, this technique is associated with a relative long scan time and sensitive to patient motion often resulting in poor image quality (1,2). Low-dose Gadolinium-enhanced 3D peripheral MRV is promising, but in patients with fresh thrombosis the puncture of a foot vein is som...

High-resolution magnetic resonance venography (HR-MRV) of intracranial subependymal veins using a two-dimensional Fourier-transform time-of-flight technique was performed on normal volunteers and clinical cases of cerebral disease. For the pulse sequence, fast-field-echo sequence was used with the following parameters: TR/TE/flip angle = 34 ms/12 ms/50 deg., 256 x 256 matrix, 1 mm effective sli...

Much of the primary research of Louisiana State University’s Robotics Research Laboratory (RRL) is conducted with the help of a specially modified Denning MRV (mobile robot vehicle) III research robot (figure 1). MRV III is an excellent test bed for robotics research: It has a straightforward user interface, it is easily modified to accept new features, and it ■ The Department of Computer Scien...

The dominant and sometimes competing theories for the aetiology of complex human disease have been the common disease, common variant (CDCV) hypothesis, and the multiple rare variant (MRV) hypothesis. With the advent of genome wide association studies and of second-generation sequencing, we are fortunate in being able to test these ideas. The results to date suggest that these hypotheses are no...

BACKGROUND AND PURPOSE A noninvasive MRI method to measure cerebral oxygen metabolism has the potential to assess tissue viability during cerebral ischemia. The purposes of this study were to validate MR oxygenation measurements across a wide range of global cerebral oxygenation and to examine the spatiotemporal evolution of oxygen metabolism during focal middle cerebral artery occlusion in rat...
