【Abstract】Objective：To study the advantages and disadvantages of common green tea beverage as a new oral negative contrast agent in MRCP examination and conventional MRCP examination， and to improve the technical level of MRCP examination of biliary tract. Methods： MRCP image quality of 100 patients before and after oral administration of new tea beverage contrast agent was compared， and a self-control study was conducted. Questionnaire survey was adopted to ask patients about their examination feelings， and statistical analysis was conducted.Results：100 patients took the contrast agent， the digestive tract filling was good， the effect was satisfactory， MRCP image quality was significantly improved; The negative contrast agent of the new type of tea drink was well tolerated. Conclusion： Through rigorous theoretical analysis， the image quality of the oral negative contrast agent of new tea drinks in MRCP examination can significantly improve the safety， efficiency， low price， high comfort and easy to be accepted. It is suggested to be popularized and applied in the medical field.

MRCP是一种无创伤性高新技术，具有简便、快速、准确率高等特点，无需借助任何造影剂即可立体多角度方位显示胆道系统，发现胆管结构异常，MRCP敏感度及特异度特别好，准确度较B超及MSCT均大幅度提高，目前已经成为无创性评价胰胆管疾病的强有力方法，其诊断性能类似于内镜下逆行胰胆管造影[1-2]，是行之高效的检查方法，尤其对梗阻性胆道疾病的评估具有较高的敏感性、特异性和准确性[3]。MRCP常规检查时由于胆道与胰腺病变的影响，患者胃肠道内常含有潴留液，干扰MRCP的图像质量，导致错误诊断，胃肠道内液体同时显影，影响了对胰胆管的观察，尤其是胃窦与十二指肠横跨过右上腹，其内液体的高信号掩盖和干扰了胆总管中下段的显示，是影响MRCP图像质量的重要原因之一[4]。……
