摘要 目的:通过核磁共振成像(MRI)的特殊序列和检查方法,评价MRI在肝硬化和门脉高压早期诊断中的作用。方法:利用3DT1W/FFE和SENSEBABLANCE技术,对肝硬化和门脉高压患者及正常人各100例的信号强度及其平均标准差、肝硬化小结节的显示、门脉和胃底静脉的显示及内径进行了研究,并和常规MRI检查序列T2W/TSE进行了比较。结果:①3DT1W/FFE能显示常规扫描不能显示的肝硬化结节。②提出正常人信号强度平均标准差的最大值小于肝硬化患者的最小值,并认为在3DT1W/FFE标准差>30时,应考虑为结节性肝硬化。③SENSEBABLANCE冠状位能显示门脉高压程度及分支大小。结论:利用MRI的特殊序列和检查方法在肝硬化和门脉高压早期诊断中有重要价值。 Objective: To evaluate the diagnostic value of the special sequences and methods of MRI in liver cirrhosis and portal hypertension. Methods:100 cases of liver cirrhosis were examined by 3DT1W/FFE and SENSE-BABLANCE sequences and compared with normal livers. Results: ① 3DT1W/FFE imaging has clear advantage over conventional scan in detecting cirrhotic nodules. ② The peak of signal intensity ASD (average standard deviation) in normal livers and the minimum of signal intensity ASD in liver cirrhosis cases were found . If signal intensity standard deviation in liver was over 30, liver cirrhosis should be considered. ③ The degree of hypertension and the size of portal vein and its branches were evaluated by SENSE-BABLANCE sequences. Conclusion: MRI special sequences and methods play a significant role in the early diagnosis of liver cirrhosis and portal hypertension.
