心脏磁共振结合心脏超声对左心室功能评价的临床应用

The Clinic Application of Cardiac Magnetic Resonance Imaging in Evaluation the Cardiac Function Combined with Echocardiography

目的应用心脏磁共振(CMR)评价左心室功能,并通过对比UCG探讨CMR在临床中的应用价值。方法选取行CMR检查患者22例,采用SiemensMagnetom Skyra3.0T超导型磁共振仪进行扫描,均进行MR平扫、电影扫描,所有检查者行CMR前均行超声心动图检查。结果对比CMR和超声心动图测量所得EDV,ESV,EF值,CMR测量EDV,EF值较超声心动图略低,ESV值高于超声心动图。两组间EDV,ESV值无统计学意义(P>0.05),EF值具有统计学差异(P<0.05)。结论 CMR在评价左心室功能方面准确性及可靠性好,评价指标全面,可应用于各种复杂疾病心脏功能的检查。

Objective To evaluate the left ventricular function by cardiac magnetic resonance imaging（ CMR） ,and to explore the fesibility and value of CMR in clinical application.Methods The lefe ventricular function of twenty-two patients were evaluated by Siemens Magnetom Skyra 3.0T magnetic resonance Machine.Before that,all patients underwent echocardiographic measurements.Results The value of EDV,ESV,EF measured by CMR and echocardiography showed the EDV,EF measured by CMR was slightly lower than the value meas-ured by echocardiography;The ESV measured by CMR was slightly higher than the value measured by echocardiography.Linear correlation a-nalysis of the two methods were highly correlated（r=0.843-0.936）.The consistency was also higher.The value of EDV,ESV had no statisti-cal significance（P〉0.05）.While the value of EF was statistically significant（P〈0.05）.Conclusion CMR shows the left ventricular func-tion with good accuracy,reliability and comprehensive assessment criteria,and can be used to check cardiac function in a variety of complex diseases.
