口服钆喷酸葡胺在3.0T MR胰胆管成像中的应用

Application of Oral Gadopentetic Acid Dimeglumone Salt Solution in Magnetic Resonance Cholangiopancreatography at 3.0T MR

目的探讨钆喷酸葡胺作为胃肠道阴性对比剂在3.0T磁共振胰胆管成像中的应用价值。方法对39例病人分别在口服钆喷酸葡胺前后进行磁共振胰胆管成像检查,得到两组对照图像,请放射科3位高年资医生对两组图像进行评估后行统计学分析。结果采用χ2检验分析,χ2值为62,P<0.001,两组差异具有显著性意义。结论口服钆喷酸葡胺后行磁共振胰胆管成像,图像中胃肠道液体信号几乎完全被抑制,既经济又方便,在磁共振胰胆管成像中更应该值得推广应用。

Objective：To investigate the value of oral gadopentetic acid dimeglumone salt solution as a negative gastrointestinal contrast agent in 3.0T magnetic resonance cholangiopancreatography. Methods： Thirty-nine patients were studied. Routine MRCP were performed on the same patients in the two groups before and after taking oral gadopentetic acid dimeglumone salt solution. Three experienced radiologists evaluated the images,and analyzed with statistical software. Resuits：The differences between the two groups were statistically significant（x^2= 62,P〈0.001）. Conclusion： MRCP with oral gadopentetic acid dimeglumone salt solution shows the suppression of water signal from the gastrointestinal tract. It is an economical and convenient method that can be used in magnetic resonance cholangiopancreatography.
