Role of Diffusion Weighted Magnetic Resonance Imaging in Cerebral Venous Thrombosis (CVT)

Dr. Kalyani Bankupalli

Abstract: Cerebral venous thrombosis (CVT) is a cause of stroke with diverse etiologies and varied clinical presentations. The Pathophysiology of CVT with associated venous stroke appears to differ from arterial strokes. Acute arterial strokes show cytotoxic edema, whereas venous strokes are thought to contain vasogenic and interstitial edema due to venous congestion. Conventional MRI cannot differentiate between vasogenic edema and cytotoxic edema.
