手推法在肝脏MRI动态增强扫描中的临床应用

目的探讨手推法对肝脏磁共振动态增强效果的影响。方法因临床怀疑有肝脏疾患而在我院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。

The clinical application of hepatic MRI dynamic contrast- enhanced effect with the hand bolus injection method

Objective To evaluate the hepatic MRI dynamic contrast-enhanced effect with the hand bolus injection method.Methods Clinician doubt liver disease were randomly divided into two groups,636 cases were using hand bolus injection method,and 98 cases were using mechanic power injections,then the different enhacement 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.Conclusion Better enhanced effect could be obtained by using the hand bolus injection method.This method was an simple,accurate,safe and reliable method can be used widely in the more fundamental hospitals.Standardizing operation and improving nursing quality are the key to the successful studies.
