Brief Summary

Cerebral venous thrombosis (CVT) is a rare disease, and with poor prognosis. Computed tomography (CT) andmagnetic resonance imaging (MRI) are the most commonly used image modalities for patients with non-specific neurologic symptoms. We are going to assess the accuracy of CT and MRI in the differential diagnosis of CVT and cerebral venous sinus thrombosis (CVST).
