摘要
目的 提高对先天性主动脉缩窄表现 ,特别是MRI表现的认识。方法 回顾分析 2例主动脉缩窄的X线平片 ,主动脉造影和MRI所见 ,并作文献复习。结果 X线平片和主动脉造影有特征性改变 ,但MRI即能显示主动脉缩窄的部位、范围、程度及并发症 ,又能反应压力差的功能学变化。
Objective To improve the knowledge of imaging manifestations of congenital coarctation of the aorta,especially in MRI.Methods Two cases of coarctation of the aorta with the materials of X ray plain film,aortogram and MRI were retrospectively analysed.Relating articles were reviewed.Results X ray plain film and aortogram could manifest the diagnostic change of coarctation of the aorta,but MRI could manifest not only the location,extension,degree and complication but functional change of pressure difference.Conclusion MRI is the best method of noninvasion for diagnosis of congenital coarctation of the aorta.
