摘要
目的 探讨低场3D CES MRA的方法和评价其在腹部血管及与其相关疾病诊断的应用价值。方法 使用日立AIRIS-Ⅱ comfort 0.3T MR,采用小剂量钆造影剂注射扫描预测造影剂到达靶血管的峰值时间,对 23 例腹部血管及与其相关疾病患者行3D-CES MRA。结果 23例全部一次成功,图像质量均达到诊断要求。3D-CES MRA能清晰显示腹主动脉及其主要分支的解剖结构和各种病变。结论 3D-CES MRA是一种诊断腹部血管及与其相关疾病的新方法,只要技术应用得当,低场磁共振同样可以取得符合临床诊断要求的图像。
Objective To evaluate the method and the application value of low field three-dimensional contrast enhanced subtraction MR angiography in abdominal blood vessels and relative diseases. Methods A total of 23 patients underwent 3D-CES MRA with AIRIS-Ⅱ comfort 0.3T MR made by HITACHI. The small volume Gd-DTPA were used for injection scanning to measure the peak value time of Gd-DTPA arrived at the target blood vessel. Results 3D-CES MRA was successful in the diagnostic examination of 23 cases. The images were fine and distinct for diagnosis. 3D-CES MRA clearly showed the anatomical structure of abdominal aorta, the main branches and various lesions. Conclusion 3D-CES MRA is a new method in diagnosing of abdominal blood vessels and relative diseases. It was proved that clear image for diagnosis can also be obtained by low field MR imaging system if this technique was properly applied.
