摘　　要：目的:提高对静脉窦血栓的MRI表现的认识。方法:回顾性总结分析15例静脉窦血栓的病例,包括临床表现、影像学检查。所有患者均采用Philips 1.5T核磁共振扫描机扫描,头颅MRI平扫加增强加MRV。结果:全部患者表现不一,基本病程1 h～6个月。头晕者2例,头痛、发热者2例,4例有肢体抽搐,不省人事3例。静脉窦血栓的MRI平扫表现为脑内单发或多发异常信号,类似脑出血、脑梗死或脑炎改变,部分类似转移瘤,也可表现为正常,MRV可见颅内静脉窦显示欠清,中断或充盈缺损区。结论:MRI诊断静脉窦血栓准确率高,影像表现有特征性,图像直观,直接显示血栓部位静脉窦中断或充盈缺损,是一种无创、直观可靠的检查方法,能更好地协助临床诊断及治疗。Objective To improve the MRI performance of venous sinus thrombosis awareness. Method We analyzed 15 cases of ve- nous sinus thrombosis,including clinical manifestation ,imaging examination retrospectively. All patients used Philipsl. 5T nuclear magnetic resonance scarmer seanning,MRI plain scan and enhanced MRV. Results All patients showed a basic course of disease from 1hours to 6months. Dizziness was in 2 cases ,headache and fever was in 2 cases ,limb convulsions was in 4 cases ,becoming unconscious was in 3 ca- ses. Venous sinus thrombosis on plain MRI scan showed intracerebral solitary or multiple abnormal signal,it was similar to cerebral hemor- rhage, cerebral infarction or encephalitis change, and partly similar metastasescan also behaved as normal. MR V visible intracranial venous sinus showed less clearance,interrupt or filling defect area. Conclusion MRI diagnosis of cerebral venous sinus thrombosis with high accu- racy,imaging findings are characteristic,image is visual, and it can directly display the thrombi sinus interruption or filling defect, so it is a noninvasive, reliable examination method, and it can better facilitate the clinical diagnosis and treatment.
