BACKGROUND Isolated thrombosis of the deep cerebral venous system is very rare and is associated with a poor prognosis. Antithrombin III (AT III) deficiency is a disorder of hypercoagulability associated with deep venous thrombosis and recurrent pulmonary emboli. We report a case of an 18-year-old man who presented with spontaneous thrombosis of the deep cerebral veins and straight dural sinus ...

We report a case of spontaneous intracranial hypotension that underwent cerebral angiography. The angiogram showed prominence of the veins and venous phase of the angiogram. This is thought to be secondary to decreased intracranial pressure and subsequent dilation of the venous system to attempt to replace the lost intracranial CSF volume. In situations in which the typical clinical presentatio...

BACKGROUND AND PURPOSE The effect of various contrast-dose regimens for cerebral MR venography (MRV) has not been previously evaluated at 3T, to our knowledge. Our purpose was to evaluate and compare the diagnostic image quality resulting from half-versus-full-dose contrast regimens for high-spatial-resolution 3D cerebral MRV at 3T. MATERIALS AND METHODS Forty consecutive patients with known ...

BACKGROUND AND PURPOSE A high incidence of arteriovenous malformations (AVMs) is associated with hereditary hemorrhagic telangiectasia type 1. Endoglin, the gene mutated in this disorder, is expressed at reduced levels on blood vessels of these patients. Since endoglin is a component of the transforming growth factor-beta receptor complex critical for vascular development and homeostasis, we de...

INTRODUCTION: Susceptibility-weighted imaging (SWI) exploits phase shift itself to enhance contrast caused by the susceptibility differences between tissues, and creates contrast between deoxygenated veins and the neighboring tissue in the brain [1]. SWI provides high-spatial resolution, blood-oxygen-dependent, venography without requiring contrast media. Clinically, SWI has been applied to the...

Cerebral venous oxygen saturation (SvO2) is an important biomarker of brain function. In this study, we aimed to explore the relative changes of regional cerebral SvO2 among axonal injury (AI) patients, non-AI patients and healthy controls (HCs) using quantitative susceptibility mapping (QSM). 48 patients and 32 HCs were enrolled. The patients were divided into two groups depending on the imagi...
