摘要 目的评价钆喷酸葡胺(Gd—DTPA)在抑制胃肠道高信号改善磁共振胰胆管成像(MRCP)图像质量中的作用。方法选取2ml静脉用Gd—DTPA配制成100ml浓度为0.01mol/L的稀释液作为MRCP口服用胃肠道对比剂。对22例疑有胰胆管病变的患者分别于口服Gd—DTPA前及口服5分钟后行MRCP检查,分析前后胰胆管及病变的显示情况。结果22例患者口服Gd—DTPA稀释液后MRCP图像上胃、十二指肠内潴留液高信号被明显抑制,使得胰胆管树各解剖结构的对比度提高,显示更加清楚,图像质量较常规明显改善。结论口服钆喷酸葡胺稀释液能明显提高MRCP的成像质量,对诊断胆胰系病变具有重要的临床应用价值。
