【摘要】：目的对比分析磁共振3D BRAVO序列与TRICKS序列对脑静脉血栓检出的优劣,探讨脑静脉血栓的MR检查方法.方法回顾性分析云南省第二人民医院2011年1月至2014年6月临床确诊脑静脉血栓的40例,所有患者均先行TRICKS序列扫描,结束后再进行3D BRAVO序列扫描,扫描结果分为静脉窦、深静脉及浅静脉组3组进行对比分析,分别评价2种序列对静脉血栓的检出率并对结果进行统计分析.结果 3D BRAVO及TRICKS序列对静脉窦组血栓的检出率分别为48例(98.0%)及49例(100%),深静脉组血栓检出率13例(92.9%)及14例(100%),2组中两种方法无明显统计学差异(P0.05),浅静脉组血栓检出率12例(66.7%)及18例(100%),2种方法有明显差异(P0.05).结论 3D BRAVO序列可以精确显示血栓的静脉部位、累及范围,尤其对浅静脉组的血栓显示更具优势,具有较好临床应用价值,结合TRICKS序列3D重建显示更为直观.
[Abstract]:Objective to compare the advantages and disadvantages of 3D BRAVO sequence and TRICKS sequence in detecting cerebral venous thrombosis (CVT), and to explore the method of MR in detecting cerebral venous thrombosis (CVT). Methods from January 2011 to June 2014, 40 patients with cerebral venous thrombosis in Yunnan second people's Hospital were retrospectively analyzed. All the patients were scanned with TRICKS sequence first, then 3D BRAVO sequence scan was performed after that, the results were divided into venous sinus. The detection rate of venous thrombosis in deep vein group and superficial vein group was evaluated and the results were statistically analyzed. Results the detection rate of thrombus in venous sinus group by 3D BRAVO and TRICKS was 98.0% and 49 (100%) respectively, 13 cases (92.9%) in deep vein group and 14 cases (100%) in deep vein group. There was no significant difference between the two methods (P0.05), 12 cases (66.7%) of superficial vein group and 18 cases (100%) of thrombus detection rate, there was significant difference between the two methods (P0.05). Conclusion 3D BRAVO sequence can accurately show the location and extent of thrombus, especially in superficial vein group, which has a good clinical value, and is more intuitionistic combined with 3D reconstruction of TRICKS sequence.
