摘　　要：目的探讨手推法对肝脏磁共振动态增强扫描效果的影响．方法因临床怀疑有肝脏疾患而行肝脏动态增强扫描者，随机分组．手推法行肝脏动态增强扫描636例，高压注射器法行肝脏动态增强扫描98例．观察腹主动脉、下腔静脉、正常肝实质在动脉期、门脉期、实质期的信号强度．结果手推法与高压注射器法比较，腹主动脉、下腔静脉和正常肝实质动态增强扫描各期信号强度均无显著性差异（P〉0．05）．结论手推法在肝脏磁共振动态增强扫描中能取得良好效果，而且简单、准确、安全、可靠，更适用于基层医院广泛应用．Objective To evaluate effect of hand bolus injection method on hepatic dynamic contrast-enhanced MRI. Methods Clinicians doubted liver disease were randomly divided into two groups, 636 cases were used with hand bolus injection method,and 98 cases were used with mechanic power injections,then the different enhancements of abdominal aorta,venacava,hepatic were observed in the period of abdominal aorta,venacava,hepatic. Results It was no obvious difference between hand bolus injection method and mechanic power injections（P 〉 0.05）. Conclusion Better enhanced effect could be obtained by using hand bolus injection method. This method was a simple,accurate,safe and reliable and can be used widely in the more fundamental hospitals.
