Diagnostic Value of Doppler Ultrasound to Cerebral Venous Thrombosis

All the clinicians have consented the value of Doppler ultrasound in intracalvarium and extracalvarium arterial system disease, but haven't put enough emphasis on the cerebral venous system. Cerebral venous thrombosis is a rare cerebrovascular disease, its diagnosis mainly depends on magnetic resonance venography and digital subtraction angiography, which are only morphology examination and can't provide the information of hemodynamics for clinic. Doppler ultrasound can detect hemodynamics of the cerebral venous system, and it can offer plentiful information for diagnosis, treatment and prognosis of cerebral venous thrombosis(CVT). This paper reviews application of Doppler ultrasound in the cerebral venous system, with the aim to improving the recognition of the evaluation effect of ultrasound on hemodynamic of the cerebral venous system by doctors and clinicians.
