多层螺旋CT对主动脉夹层的诊断价值

Multi-spiral CT Diagnosis for Aortic Dissection

    摘要
  • 摘要: 目的:探讨多层螺旋CT对主动脉夹层的诊断价值。方法:对15例主动脉夹层患者行多层螺旋CT全主动脉血管造影并进行二维和三维图象重建,重建方法包括多平面重组(MPR),曲面图象重组(CPR),表面遮盖成像(SSD),最大密度投影(MIP)。结果:经过正确诊断和分型的15例主动脉夹层在MPR,CPR图象中,全部病例均显示AD的真假腔,剥离的内膜片,附壁血栓及钙化,其中12例还显示内膜破口。AD的SSD,MIP图象立体感强,直观地显示主动脉夹层与周围器官的关系。结论:MSCT对主动脉夹层的诊断,分型以及破裂口的定位是有效,无创的方法。

     

    Abstract: Purpose To evaluvate the multi-slice spiral CT (MSCT) technique in diagnosing the aortic dissection (AD). Methods 15 cases with AD were performed by whole aorta MSCT angiography,all data were processed with 2D and 3D reconstructions,the main methods included: MPR,CPR,SSD and MIP. Results All cases were diagnosed as arotic dissection and classified correctly. In 15 cases, true and false cavity, intimal flap, mural thrombus and calcification of AD were displayed. In 12 of all cases, the location of intimal rupture were displayed. The SSD and MIP images of AD displayed the relationship between AD and neighboring organs clearly and directly. Conclusion MSCT is an effective and non-invasive method in diagnosis, classification and location of intimal rupture of AD.
