Comparison of BRAVO Sequence and TRICKS Sequence on Cerebral Venous Sinus Thrombosis / 昆明医科大学学报

ABSTRACT

Objective To compare the advantages and disadvantages of 3D BRAVO and TRICKS for detecting cerebral venous sinus thrombosis (CVST) and to explore the MR scanning methods on CVST.Methods A retrospective analysis was conducted on 40 patients who were diagnosed with CVST in the Fourth Affiliated Hospital of Kunming Medical University from January 2011 to June,2014.All the patients underwent TRICKS scan and 3D BRAVO examination and were classified into 3 groups based on dural venous sinuses,deep cerebral vein and superficial cerebral vein.Detection rates of TRICKS and BRAVO were evaluated and the results were analyzed.Result Detection rates of dural venous sinuses by TRICKS and BRAVO were 98.0％ and 100％ respectively.Detection rates of deep cerebral vein were 92.9％ and 100％ respectively.No significant difference was found (P＞0.05).Detection rates of superficial cerebral vein were 66.7％ and 100％ respectively.Significant difference was found between the two (P＜0.05) Conclusion BRAVO technology can clearly demonstrate the details of CVST,especially in superficial cerebral vein.With the combination use of TRICKS sequences,it will be of higher diagnostic value.
