We have developed a procedure to image the major veins of the brain using three dimensional magnetic resonance imaging sequences. This procedure is based on the selective enhancement of blood vessels following intravenous administration of contrast media such as gadolinium. A simple subtraction is performed between the post-contrast and pre-contrast MR images after correcting for overall intens...

thromboembolic phenomena are the serious consequences of assisted reproductive technology. we present a case of cerebral sinus vein thrombosis (cvst) following ovarian hyper stimulation syndrome (ohss). ten days after recovering from ohss, the patient presented in the emergency department with thunderclap headache. her magnetic resonance venography (mrv) showed occluded left transverse sinus an...

We present a case of cerebral sinus vein thrombosis (CVST) following ovarian hyper stimulation syndrome (OHSS).

289 Over the past decade, neurologists and neuroradiolo-gists have paid increasing attention to the role of the intracranial venous system in cerebrovascular diseases, such as dural sinus steno-occlusive diseases. The intra-cranial venous system has been evaluated traditionally during the venous phase of conventional catheter digital subtraction angiography (DSA). In fact, DSA is still the gold...

Carotid cavernous fistula is a serious vascular pathology that commonly misdiagnosed due to clinical signs overlap with several other pathologies and the need for sensitive imaging techniques, most notably digital subtraction angiography, make diagnosis. Here we present case of carotid mimicking orbital cellulitis, ultimately diagnosed magnetic resonance venography.
