Object:To investigate the quality of 3D- CE- MRA acquired by the way of injecting the contrast agent via bilateral e-blow vein. Method:To analysis the quality of 100 cases of 3D- CE- MRA acquired by the way of injecting the contrast agent via right eblow? vein and left eblow vein randomly and separately. Result:The quality of 3D- CE- MRA was good acquired by the way of in-jecting the contrast agent via right eblow vein without contrast agent shunting, the quality of 9 cases of 3D- CE- MRA was poor with the contrast agent shunting and the diagnostic value decrease. Occlusion:It is best to inject the contrast agent via right eblow vein when perform 3D- CE- MRA.
