1、［經(jīng)典］多層螺旋CT在診斷主動(dòng)脈夾層中的價(jià)值多層螺旋CT在診斷主動(dòng)脈夾層中的價(jià)值［摘要］目的：回顧性分析主動(dòng)脈夾層(aorticdissection,AD)的多層螺旋CT造影結(jié)果,然后通過正確率來(lái)探討螺旋CT診斷AD的價(jià)值。方法：50例AD患者全部行平掃及增強(qiáng)掃描，并結(jié)合多平面重組、曲面重組等方法來(lái)顯示AD及穿透潰瘍，根據(jù)Stanford分類法分型。結(jié)果:對(duì)50例AD患者造影結(jié)果進(jìn)行分析，分為A型27例,B型23例，所有患者均顯示主動(dòng)脈夾層典型征象；主耍CT表現(xiàn)為主動(dòng)脈壁呈新月型或環(huán)形增厚，無(wú)內(nèi)膜破

2、裂形成的雙腔主動(dòng)脈征象,增強(qiáng)掃描假腔無(wú)強(qiáng)化；內(nèi)膜鈣化向內(nèi)移位14例；穿透性潰瘍征6例;并發(fā)心包、縱隔及胸腔積液和積血共30例。結(jié)論:螺旋CT能夠清楚顯示夾層的部位、范圍及并發(fā)癥，可作為主動(dòng)脈夾層的首選檢查及隨訪方法。［關(guān)鍵詞］多層螺旋CT;主動(dòng)脈夾層;診斷價(jià)值［中圖分類號(hào)］R543［文獻(xiàn)標(biāo)識(shí)碼］C［文章編號(hào)］1674-4721(2010)07(a)-106-02ThevalueofthespiralCTinthediagnosisofaorticdissectionTANGXiaoming(Radi

8、有明顯上升的趨勢(shì)，早期正確診斷是良好預(yù)后的關(guān)鍵，螺旋CT血管造影為非創(chuàng)性血管成像技術(shù)，它在大血管病變的診斷、治療方案的擬定及術(shù)后的療效評(píng)價(jià)方面有重要的臨床應(yīng)用價(jià)值，多層螺旋CT(multislicespiralCT,MSCT)由于掃描速度快,覆蓋范圍廣，短時(shí)屏氣即可完成主動(dòng)脈全程的掃描，加上強(qiáng)大的圖像后處理功能，非常適宜于主動(dòng)脈病變的檢查[1]。筆者收集了經(jīng)16層螺旋CT檢查診斷的AD患者50例，旨在探討多層螺旋CT在AD診斷中的臨床應(yīng)用價(jià)值,現(xiàn)報(bào)道如下：1資料與方法
