This study aims to explore magnetic resonance High-resolution Variable Flip Angle Turbo-Spin-Echo(T1 SPACE) technique for accurate staging of Cerebral Venous Sinus Thrombus(CVT). CVT patients confirmed by Computed Tomographic (CT) were randomly divided into three groups according to the time from the onset of symptoms to T1 SPACE. Signal to Noise Ratio(SNR) and Contrast to Noise Ratio(CNR) between thrombus and gray tissues/white tissues were calculated on every thrombus segments and difference between different groups were analyzed. Results indicate that T1 SPACE has the potential to be a promising tool for accurate diagnosis and staging of CVT.
