摘要
目的:探讨CT三维重建技术在DeBakeyⅠ、Ⅱ型主动脉夹层方面的应用价值,并对各种处理技术进行比较研究。方法:回顾性总结36例DeBakeyⅠ、Ⅱ型主动脉夹层的三维重建技术,应用多层面重建(MPR),曲面重建(CPR),容积重建(VR),表面重建(SSD),最大密度投影(MIP)及仿真内窥镜成像技术(VE)等对主动脉夹层进行图像重建。结果:MPR和CPR能较好显示病变范围、大小及病变细节,而MIP、VR和SSD能良好地显示管壁钙化情况和病变空间关系,VE可显示主动脉夹层的内膜破口情况、内膜片与血管关系。结论:CT是诊断主动脉夹层的有效方法,对临床及时诊断和指导手术治疗具有重要价值。
Objective：To evaluate CT 3D reconstruction techniques in type-Ⅰ,Ⅱ aortic dissection, and then study the comparison of all the techniques.Methods： CT 3D reconstruction techniques in thirty-six cases of DeBakey Ⅰ,Ⅱtype aortic dissection were summaried retrospectively. The 36 3D reconstruction techniques were multiplanar reconstruction（MPR）, curved planar reconstruction（CPR）, volume reconstruction（VR）, surface shaded dispay（SSD）, Maximum intensity projection（MIP）, and virtual endoscopy（VE）. Results： Two dimensional imaging （MPR and CPR） could dearly show the extent,size and details of lesions. The space relationship and calcification of aorta were displayed in three dimensional imaging （ SSD, VR and MIP）. The presence of infimal flap and reentry of dissection could be clarified by VE. Conclusion： CT 3D reconstruction techniques is effective in diagnosis of aortic dissection, and is of great value in guiding clinical treatment.
