摘要：

目的　评价使用枸橼酸铁铵后 3D MRCP图像的改善程度。方法　本组共收集MRCP病人 3 0例。在服用枸橼酸铁铵前、后以相同的采集参数对其行 3D MRCP成像。图像评价从胃肠信号消除情况和图像质量改善情况两方面进行。结果　使用造影剂后胃部的对比信噪比由 7.0 64± 3 .85 3降至 1.0 41± 0 .45 9,十二指肠则由 5 .494± 3 .916降至 1.93 1± 2 .3 17,两者的P值均小于 0 .0 0 1;MRCP的图像质量由造影前的 2 .83 3± 2 .0 5 2增至 9.13 3± 2 .0 3 0 ,P <0 .0 0 1。结论　使用枸橼酸铁铵几乎可完全消除 3D MRCP图像中的胃肠信号 ,明显改善图像质量。
