摘　　要：目的:探讨非传统方法对于简化磁共振静脉成像的可行性及其临床应用价值。方法:将30例患有肝占位病变需要增强的患者分为3组,每组10例,分别为对照组、实验组1、实验组2。对照组以常规方式用高压注射器行MR血管成像,实验组1、实验组2均以30 mL普通注射器替代高压注射器,以手推方式快速将造影剂推注入手背静脉待循环进入静脉期后即行血管造影。对照组使用30 mL钆喷酸葡胺,实验组1使用20 mL钆贝葡胺,实验组2使用20 mL钆喷酸葡胺(实验组药物剂量均小于对照组),后再直观评价图像质量及测定3组图像相对应区域的信号值。结果:实验组1图像清晰,门静脉走向、轮廓及其分支显示清楚,其信号值与对照组相比,P>0.05,无统计学差异;实验组2图像模糊,门静脉走向、轮廓及其分支显示不清,其信号值与对照组相比,P<0.05,有统计学差异。结论:钆贝葡胺静脉注射的方法对于简化磁共振腹部静脉成像技术在理论、技术上有一定可行性,在满足常规增强扫描的同时,亦可得到达诊断质量的静脉成像,并简化了操作,减少了药物剂量,增加了诊断信息并且相对降低了患者的检查费用。Objective： To explore the feasibility and clinical application value of hand push injection of gadolinium Tony dimeglumine to perform MR portal venography. Methods： Thirty patients suffering from liver disease were divided randomly into 3 groups, ten patients in each group. 20 mL of gadolinium Tony meglumine were quickly injected into the vein of the patients by hand push injection in the first group. 20 mL gadolinium spray acid meglumine were quickly injected into the vein of the patients also by hand push in the second group. 30 mL gadolinium spray acid meglumine were injected into the vein of the patients in the control group by high pressure syringe to perform portal venography. Then determine the signal value of the corresponding region of interest in the three groups and evaluated the image quality. Result： The image of the potal vein and its branches showed clearly in the first group, compared to the control group, the signal value had no significant difference（P〉0.05）. In contrast, the image of the portal vein and its branches in the second group was unclear and fuzzy, compared to the control group, there were significant differences between the signal values （P〈0.05）. Conclusion： Using gadolinium Tony meglumine as the contrast agent by hand push to perform MR portal venography has clinical application value. It can simplify the operation and can also achieve the same image quality as using gadolinium spray acid meglumine with a high pressure syringe and thus can reduce the cost of examination.
