摘要
目的:探讨64排螺旋CT血管造影技术(CT angiography,CTA)及各种图像重建技术在主动脉夹层(AD)中的诊断价值。方法:确诊为AD的32例患者,均行64排CTA检查,并对原始数据进行多平面重组(MPR)、曲面重建(CPR)、最大密度投影(MIP)以及三维容积成像(VR)后处理。结果:32例患者CTA均显示内膜片、内膜破口、真假腔及分支血管受累情况。结论:64排螺旋CT血管造影能快速、准确、无创地诊断主动脉夹层,为临床选择治疗方案提供更多的信息。
Objective： To investigate the diagnositic value of 64-detetor spiral CT angiography（CTA） and various types of imaging reconstruction techniques in aortic dissection.Methods： 32 patients with aortic dissection（AD） all underwent 64-detetor spiral CTA,and original image reconstruction were postprocessed by multiplanar reformation（MPR）,curved planar reconstruction（CPR）,maximum tensityprojection（MIP） and volume rendering（VR）.Results： CTA showed clearly the location of crevasse,the true and false lumens and the involvement of the branches in all 32 patients.Conclusion： 64-detetor spiral CTA is a rapid,accurate and non-invasive method for diagnosis of AD,which can provide more information for clinical treatment.
