BACKGROUND AND AIM Ocular gaze deviation (OGD) is a well known clinical observation (Prevost's sign) in patients with acute cerebral ischemic stroke. Although OGD has been observed on CT in acute stroke, no investigation has quantified the degree of OGD in acute stroke. MATERIAL AND METHODS A blinded prospective comparison was performed of two groups of(More)
The lifetime risk of developing a cerebral aneurysm is about 5%. For some patients, aneurysms can be reasonably managed by conservative measures, including periodic clinical and imaging surveillance. However, the definitive treatment of cerebral aneurysm disease requires securing the aneurysm by surgically excluding it from the cerebrovascular circulation.(More)
BACKGROUND AND PURPOSE The only Food and Drug Administration-approved implant for managing intracranial stenosis is the Wingspan stent. Modification of the standard Wingspan stent delivery procedure has not been previously reported. MATERIAL AND METHODS Retrospective, single-patient, technical report. RESULTS Following uneventful balloon angioplasty, a(More)
With the increased availability of laboratory tests, glutamic acid decarboxylase (GAD) antibody-positive limbic encephalitis has become an emerging diagnosis. The myriad symptoms of limbic encephalitis make the diagnosis challenging. Symptoms range from seizures, memory loss, dementia, confusion, to psychosis. We present a case of a 21-year-old female with(More)
Interest in clinical brain magnetic resonance imaging using 32-channel head coils for signal reception continues to increase. The present investigation assesses possibilities for improving diffusion-weighted image quality using a 32-channel in comparison to a conventional 12-channel coil. The utility of single-shot (ss) and an approach to readout-segmented(More)
A simple and precise method has been developed for the determination of traces of vanadium(V), using 4-(2 pyridyl azo) resorcinol, in natural water samples, containing very high concentrations of uranium. CDTA-pyrophosphate buffer has been used for masking interferants, including uranium which otherwise interferes above 125 ppb. The reaction of vanadium(More)
BACKGROUND Safety and efficacy outcomes are lacking for embosurgery of the distal internal maxillary artery (IMax) using detachable platinum fibered coils (DPFCs) in patients with uncontrollable epistaxis. METHODS A retrospective analysis was conducted on patients treated October 2006 through May 2009 with a diagnosis of uncontrollable or recurrent(More)
