3.0T磁共振在腹部胰胆管成像中的应用

Application of 3.0T MRI in abdominal MRCP

目的探讨3.0T磁共振在腹部胰胆管水成像中优势及其应用。方法搜集我院2011年1月～2011年4月进行腹部磁共振检查的患者50例,采用西门子Verio3.0T磁共振,8通道相阵控腹部线圈,haste序列,spair序列及MRCP胰胆管成像序列进行轴位相扫描。结果采用3.0T磁共振的haste序列能够在自由呼吸的状态下,缩短扫描时间同时获得高质量的图像;spair序列具有很好的脂肪抑制效果,能极大的提高对病变的显示;与haste技术结合的MRCP序列能对胰管、肝内胆管、胆囊、胆总管的病变显示的更加清楚。结论西门子3.0T磁共振并行采集技术及haste、spair序列在腹部扫描中,能获得高质量的图像。

Objective To discuss the application and ascendancy of 3.0 T MRI in abdominal MRCP. Methods Fifty patients underwent 3.0 T MRI scanning using haste, spair and 2D MRCP sequences from January to April 2011. Results The haste sequence can shorten scan time and keep the high image quality while free breathing. The spair sequence can dis- play the disease enormously and have the better fat--suppression. Otherwise, 2D MRCP sequence with haste technique can clearly discover diseases of pancreatic duct, intrahepatic bile duct, gallbladder and common bile duct. Conclusion The 3.0 T MRI can obtain high quality image in abdomen scanning while using haste spair sequences and iPAT technique.
