【摘要】：目的： 1探討磁敏感加權(quán)成像(SWI)及磁共振靜脈血管成像(MRV)技術(shù)對(duì)正常腦靜脈系統(tǒng)的顯像價(jià)值。 2探討磁敏感加權(quán)成像(SWI)及磁共振靜脈血管成像(MRV)技術(shù)對(duì)腦靜脈血栓的診斷價(jià)值。 材料和方法：選取2013年3月至2014年3月期間在中南大學(xué)湘雅二醫(yī)院神經(jīng)內(nèi)科就診,按2006年Ahmed Idbaih的標(biāo)準(zhǔn)經(jīng)臨床及影像診斷為腦靜脈血栓的患者20例,其中男性12例,女性8例,年齡8-67歲,平均年齡45+2.22歲。正常組40例,男性17例,女性23例,年齡20-50歲,平均34+1.23歲。 兩組均進(jìn)行MRI常規(guī)平掃、MRV及SWI序列成像,然后比較SWI和MRV對(duì)正常腦靜脈系統(tǒng)及腦靜脈系統(tǒng)血栓的成像價(jià)值。 結(jié)果： 1SWI及MRV對(duì)正常腦靜脈系統(tǒng)的成像比較：SWI和MRV對(duì)上矢狀竇、橫竇及直竇的顯像率差異無(wú)統(tǒng)計(jì)學(xué)意義(P=I)；MRV對(duì)下矢狀竇的顯像率較SWI高(P0.05),MRV對(duì)乙狀竇的顯像率較SWI高(P0.01),兩者差異均具有統(tǒng)計(jì)學(xué)意義。 MRV和SWI對(duì)橫竇、乙狀竇及直竇的成像質(zhì)量比較,差異有統(tǒng)計(jì)學(xué)意義(P0.01)。 SWI及MRV對(duì)大腦大靜脈及大腦內(nèi)靜脈的顯示率差異無(wú)統(tǒng)計(jì)學(xué)意義(P=I)。SWI和MRV對(duì)基底靜脈的顯示率,差異具有統(tǒng)計(jì)學(xué)意義(P0.01)。SWI對(duì)深靜脈系統(tǒng)屬支顯示數(shù)優(yōu)于MRV(P0.01)。 正常靜脈竇中,橫竇變異較多,右側(cè)優(yōu)勢(shì)型占47.5%；左側(cè)優(yōu)勢(shì)型占23%；雙側(cè)基本均衡型占29.5%。深靜脈變異中以基底靜脈變異多見(jiàn)。 2SWI及MRV對(duì)腦靜脈血栓顯像比較：MRV對(duì)腦靜脈血栓顯示率較SWI高(P0.01),SWI對(duì)繼發(fā)的腦出血及髓靜脈擴(kuò)張顯示率較MRV高(P0.01),SWI和MRV對(duì)水腫及梗塞顯示率差異無(wú)顯著性。 結(jié)論：MRV顯示靜脈竇較SWI清晰,SWI與MRV均能顯示大腦大靜脈及大腦內(nèi)靜脈,但對(duì)于較細(xì)小的基底靜脈及髓靜脈,SWI明顯優(yōu)于MRV。正常腦靜脈系統(tǒng)影像解剖變異較多。MRV對(duì)腦靜脈血栓顯像好,SWI具有對(duì)腦出血及髓靜脈擴(kuò)張成像的優(yōu)勢(shì)。
[Abstract]:Objective: 1 to evaluate the value of magnetic sensitivity weighted imaging (SWI) and magnetic resonance venography (MRV) in the imaging of normal cerebral venous system. 2 to evaluate the diagnostic value of magnetic sensitivity weighted imaging (SWI) and magnetic resonance venography (MRV) in cerebral venous thrombosis. Materials and methods: from March 2013 to March 2014, 20 patients with cerebral venous thrombosis, including 12 males and 8 females, were admitted to the Department of Neurology, Xiangya second Hospital, Central South University. According to the criteria of Ahmed Idbaih in 2006, 20 patients were diagnosed as cerebral venous thrombosis, including 12 males and 8 females. The average age was 45.2.22 years. In the normal group, there were 17 males and 23 females, aged 20-50 years, with an average age of 34. 23 years. MRI, MRV and SWI sequences were performed in both groups, and then the imaging value of SWI and MRV in normal cerebral venous system and cerebral venous thrombosis was compared. Results: there was no significant difference between SWI and MRV in the imaging rate of superior sagittal sinus, transverse sinus and straight sinus between 1SWI and MRV. The imaging rate of MRV in inferior sagittal sinus was higher than that of SWI (P0.05). The imaging rate of), MRV in sigmoid sinus was higher than that of SWI (P0.01). The imaging quality of transverse sinus, sigmoid sinus and straight sinus was significantly different between MRV and SWI (P0.01). There was no significant difference between SWI and MRV in the display rate of cerebral vein and internal cerebral vein. There was no significant difference between). SWI and MRV in displaying basilar vein. The difference was statistically significant (P0.01). SWI was better than MRV in displaying the branch of deep vein system (P0.01). In the normal venous sinus, the transverse sinus varied more, the right dominant type accounted for 47.5%, the left dominant type accounted for 23%, and the bilateral basic equilibrium type accounted for 29.5%. In the variation of deep vein, the variation of basal vein was more common. Comparison of 2SWI and MRV in cerebral venous thrombus imaging: the display rate of MRV in cerebral venous thrombosis was higher than that in SWI (P0.01), SWI higher than MRV in showing cerebral hemorrhage and dilatation of medullary vein (P0.01). There was no significant difference between SWI and MRV in showing edema and infarction. Conclusion: MRV can display venous sinus more clearly than SWI. Both SWI and MRV can display cerebral vein and internal cerebral vein, but SWI is better than MRV. for smaller basal vein and medullary vein. The imaging anatomy variation of normal cerebral venous system is much, MRV is good for cerebral venous thrombosis imaging, SWI has advantages in cerebral hemorrhage and medullary vein dilatation imaging.
