摘　　要：目的 :探讨 MRI、MRA及增强扫描在诊断脑硬膜窦血栓形成 (DST)的影像学特征和价值。方法 :回顾性分析 4 5例临床怀疑 DST的患者行 MRI、增强扫描及 MRA扫描后的影像学表现。结果 :MRI典型表现为血栓形成各时期的异常等或高信号影 ;MRA示受累硬膜窦不显影 ;增强扫描示受累硬膜窦异常对比增强。结论 :MRI、MRA及增强 MRI诊断脑硬膜窦血栓形成具有特异性 ,能够指导临床及早。Objective:To explore the characteristic and clinical value of MRI,MRA and enhanced scan in diagnosis of the dural sinus thrombosis.Methods:45 cases with clinically doubted DST were collected and examined with MRI,enhanced scan and MRA .The MRI and MRA findings were analysed.Result:MRI showed the abnormal high signal intensities during the different times of DST;MRA venography demonstrated that there were no blood flowing .Enhanced scan showed that it were all enhanced in these involved dural sinuses.Conclusion:MRI,MRA and enhanced scan are characteristic in the diagnosis of the cerebral venous thrombasis and can offer guidance for immediate clinical treatment.
