Imaging Dural Sinus Thrombosis

Abstract

The acute onset of irreversible neurological deficit is referred to as a “stroke” and is the third leading cause of death and the major cause of adult long‐term disability in the United States. Obstruction of the venous sinuses by thrombosis accounts for ˜1% of strokes. Thrombosis of the superior saggital sinus is most frequent, with involvement of transverse, sigmoid, and cavernous sinuses occurring less often. Venous thrombosis may involve the dural sinuses, the deep venous system, and the superficial cortical veins separately or in any combination. This unit describes a for imaging dural sinuses by time‐of‐flight magnetic resonance venography (MRV).
