目的 对脑静脉窦血栓形成(CVST)患者的磁共振成像(MRI)和磁共振静脉成像(MRV)影像学表现进行分析,为临床诊疗提供参考依据.方法 回顾性分析17例经数字减影血管造影(DSA)确诊CVST患者的影像学资料,全部行MRI平扫,其中行MRI平扫增强扫描检查8例,行MRV检查9例,行DSAS检查5例.结果 17例CVST患者中1例单纯乙状窦受累,1例单纯直窦受累,2例单纯横窦受累,4例单纯上矢状窦受累,4例上矢状窦和横窦同时受累,5例乙状窦和上矢状窦同时受累.MRI平扫见脑静脉窦流空效应消失,其中2例CVST患者T1WI等信号,且T2WI低信号；12例CVST患者T1WI和T2WI均为高信号；3例CVST患者T1WI低信号不均匀,且T2 WI高信号.行MRI平扫增强扫描检查8例,表现为脑静脉异常强化,静脉窦表现为不同形状的强化,窦内血栓无强化,表现为缺损或空状.DSA和MRV检查显示受累静脉窦表现为不规则的显影,狭窄影或不显影.结论 MRI联合MRV不仅可以通过直接征象和间接征象提高CVST的诊断率,而且还可以反映病理演变和评价疗效,是早期诊断CVST和动态观察治疗疗效的理想手段.
目的 對腦靜脈竇血栓形成(CVST)患者的磁共振成像(MRI)和磁共振靜脈成像(MRV)影像學錶現進行分析,為臨床診療提供參攷依據.方法 迴顧性分析17例經數字減影血管造影(DSA)確診CVST患者的影像學資料,全部行MRI平掃,其中行MRI平掃增彊掃描檢查8例,行MRV檢查9例,行DSAS檢查5例.結果 17例CVST患者中1例單純乙狀竇受纍,1例單純直竇受纍,2例單純橫竇受纍,4例單純上矢狀竇受纍,4例上矢狀竇和橫竇同時受纍,5例乙狀竇和上矢狀竇同時受纍.MRI平掃見腦靜脈竇流空效應消失,其中2例CVST患者T1WI等信號,且T2WI低信號；12例CVST患者T1WI和T2WI均為高信號；3例CVST患者T1WI低信號不均勻,且T2 WI高信號.行MRI平掃增彊掃描檢查8例,錶現為腦靜脈異常彊化,靜脈竇錶現為不同形狀的彊化,竇內血栓無彊化,錶現為缺損或空狀.DSA和MRV檢查顯示受纍靜脈竇錶現為不規則的顯影,狹窄影或不顯影.結論 MRI聯閤MRV不僅可以通過直接徵象和間接徵象提高CVST的診斷率,而且還可以反映病理縯變和評價療效,是早期診斷CVST和動態觀察治療療效的理想手段.

Objective To analyze MRI and MRV imaging of cerebral venous sinus thrombosis (CVST) formation,to provide a reference for the clinical diagnosis and treatment.Methods Seventeen cases of CVST patients confirmed by digital subtraction angiography (DSA),all underwent MRI plain scan,which MRI plain scan CT enhancement scanning 8 cases,MRV check 9 cases,DSAS check 5 cases.Results Seventeen cases of patients with CVST,one case of simple sigmoid sinus involvement,one case of simple straight sinus involvement,two cases of purely transverse sinus involvement,four cases of simple sagittal sinus involvement,four cases of superior sagittal sinus and transverse sinus were simulta-neously involved,five cases of sigmoid sinus and superior sagittal sinus involvement MRI.plain scanshow the effect of cerebral venous sinus flow void disappeared,including 2 cases of CVST patients showedT1WI signal,T2WI low signal; 12 cases of patients with CVST showed T1WI and T2WI high signal; uneven three cases of CVST patients with low intensity on T1WI and T2WI high signal.eight cases underwent MRI scan CT enhancement scanning,showed abnormal enhancement of cerebral venous,showed venous sinus strengthening of the different shapes,sinus thrombosis without strengthening,showed defect or empty like.The DSA and MRV checking showed the affected sinus,developing irregular,narrow shadow or not developing.Conclusions MRI combined with MRV not only can improve diagnosis rate of CVST by direct signs and indirect signs,but also reflects the pathological evolution and efficacy value,is the ideal means of early diagnosis of CVST and dynamic observation treatment efficacy.
