摘　　要：目的探讨T1-3D-GRE增强技术在脑静脉血栓(cerebral vein thrombosis,CVT)中的诊断价值。方法回顾性分析108例经临床确诊的CVT患者的影像学资料,在MR平扫、3D CE-MRV及T1-3D-GRE增强的扫描图像上对病灶的信号特征及分布特点进行分析,分为浅静脉组、深静脉组及静脉窦组进行病灶计数,并将病灶数据用卡方检验进行统计学分析。结果我们共检出CVT病灶172个,其中3D CEMRV检出133个,检出率77.3%,T1-3D-GRE增强检出155个,检出率90.1%。3D CE-MRV及T1-3D-GRE增强对静脉窦组及深静脉组的CVT的检出率,差异无统计学意义(P>0.05)。T1-3D-GRE增强对浅静脉组的CVT的检出率高与3D CE-MRV,差异有统计学意义(P<0.05)。结论T1-3D-GRE增强对CVT的检出率高于3D CE-MRV,尤其对皮层静脉(浅静脉)血栓的检出,是一项很有价值的检查技术。Objective To assess the value of MRI,T1-3D-GRE enhancement technique in the diagnosis of cerebral veins thrombosis.Methods 108 patients with cerebral veins thrombosis in our hospital were analyzed retrospectively.In all the images of MRI,3D CE-MRV and T1-3D-GRE enhancement the characteristic of signal and distribution of all the lesions.Divided into superficial vein group,deep vein group and venous sinus group for lesion count.The lesion data were statistically analyzed by chi-square test.Results A total of 172 CVT lesions were detected,including 1333D CE-MRV with a detection rate of 77.3%and 155 enhanced T1-3D-GRE with a detection rate of 90.1%.There was no significant difference in the detection rate of CVT between 3D CE-MRV and T1-3D-GRE in the venous sinus group and the deep vein group(P>0.05).The detection rate of CVT in the superficial vein group with T1-3D-GRE enhancement was statistically significantly different from 3D CE-MRV(P<0.05)Conclusion The detection rate of CVT enhanced by T1-3D-GRE is higher than that of 3D CE-MRV.Therefore,T1-3D-GRE enhancement technology is a valuable examination technique for the detection of venous thrombosis,especially superficial vein thrombosis.
