目的:探讨128排螺旋CT血管成像(MSCTA)的多平面重建(MPR)与容积重建(VR)技术对主动脉夹层动脉瘤(AD)的诊断价值。方法:48例AD患者行增强前后连续薄层扫描,所得图像传入工作站进行MPR及VR ,分别进行连续层面的观察分析,进行AD的DeBakey分型,并统计分析两种重建技术显示的内膜裂口、真假腔显示、血栓、斑块等的差别。结果:48例主动脉夹层动脉瘤中 DeBakeyⅠ型22例(45.83%),Ⅱ型10例(20.83%),Ⅲ型16例(33.34%),Ⅰ型显著多于Ⅱ型( P<0.05),Ⅱ型、Ⅲ型间无显著差异( P>0.05)。MPR技术显示真假腔46例(95.8%),内膜裂口48例(100%),血栓形成42例(87.5%),管壁斑块18例(37.5%)。VR技术显示真假腔43例(89.6%),管壁斑块12例(25.0%),对管腔的内膜裂口和血栓显示不清。MPR技术显示内膜裂口(100%比0%)、血栓(87.5%比0%)及管腔内斑块(37.5%比25.0%),明显优于V R技术( P<0.05或<0.01),在真假腔显示上无统计学差异( P>0.05)。结论:128排螺旋CT血管成像的多平面重建技术对主动脉夹层动脉瘤具有重要的诊断价值,优于容积重建技术。

Objective:To explore the diagnostic value of multiplanar reconstruction (MPR ) and volume reconstruc‐tion (VR) technique of 128‐slice spiral CT angiography (MSCTA) for aortic dissection (AD) .Methods :A total of 48 AD patients received continuous thin layer scanning before and after enhancement .The obtained images were de‐livered into workstation to perform MPR and VR reconstruction .Observation and analysis in continuous lay were performed in both techniques respectively .Debakey typing of AD was performed ,and intimal breach ,true and false lumen display ,thrombus and plaques etc .displayed by two reconstruction techniques were statistically analyzed .Re‐sults:Among the 48 AD patients ,there were 22 cases (45. 83% ) with DeBakey type Ⅰ ,10 cases (20. 83% ) with DeBakey typeⅡ and 16 cases with DeBakey type Ⅲ ,the incidence of typeⅠwas significantly more than that of typeⅡ (P<0.05) ,but there no significant difference between type Ⅱ and type Ⅲ (P> 0.05) .MPR technique dis‐played that there were 46 cases (95. 8% ) with true and false lumen ,48 cases (100% ) with intimal breach ,42 cases (87. 5% ) with thrombosis and 18 cases (37. 5% ) with vascular wall plaques .VR technique displayed that there were 43 cases (89.6% ) with true and false lumen ,12 cases (25.0% ) with vascular wall plaques ,but it didn't display lu‐men intimal breach and thrombus .MPR technique was significantly superior to VR technique in displaying intimal breach (100% vs .0% ) ,thrombus (87.5% vs .0% ) and lumen plaques (37.5% vs .25.0% ) ,P<0.05 or <0.01 , but there was no significant difference in displaying true and false lumen between them , P>0.05. Conclusion:The multiplanar reconstruction technique of 128‐slice spiral CT angiography possesses more diagnostic value than that of VR for aortic dissection .
