【摘要】 目的 探討多層螺旋CT血管成像(MSCTA)在主動(dòng)脈夾層動(dòng)脈瘤的診斷和臨床治療中的應(yīng)用價(jià)值。方法 15例夾層動(dòng)脈瘤均進(jìn)行了多層螺旋CT(MSCT)胸腹聯(lián)合平掃及增強(qiáng)并將原始數(shù)據(jù)在SGI工作站進(jìn)行多平面重建(MPR)、陰影表面顯示(SSD)、最大密度投影(MIP)及容積處理(VR)等后處理。結(jié)果 15例均很好地顯示了主動(dòng)脈全程及其分支,真腔、假腔、內(nèi)膜片及夾層動(dòng)脈瘤的部位、范圍得到滿意顯示。結(jié)論 MSCTA是診斷夾層動(dòng)脈瘤準(zhǔn)確、快捷、有效的首選檢查方法,具有較高的臨床應(yīng)用價(jià)值。【關(guān)鍵詞】 動(dòng)脈瘤,夾層;體層攝影術(shù),螺旋計(jì)算機(jī);血管造影術(shù)

【Abstract】 Objective To investigate the value of multislice spiral CT angiography (MSCTA) for the diagonosis and treatment of disseting aneutysm of aorta.Methods MSCT for chest and belly scanning and enhanced scanning was performed in 15 patients and the data was transferred to SGI workstation for image post processing including MPR,SSD,MIP and VR(4DAngio).Results The whole aorta and branches in 15 patients were displayed well by MSCTA.The true lumen,false lumen,intimal flap,location and extend of dissecting aneurysm were showed in all psatients satisfactorily.Conclusion MSCTA is accurate,fast and effective for the diagnosis of dissecting aneutysm. ......
