摘要
目的:研究右心室功能的心脏MR成像评价。方法:选取30例健康的患者,其中男16例,女14例,年龄19～38岁。使用德国Siemens公司SomatonAera1.5T磁共振机进行右心室短轴电影成像,使用Argus 4D VF心室功能软件分别测量了右心室射血分数(EF)、舒张末期容积(EDV)、收缩末期容积(ESV)、心搏出量(SV)、心排出量(CO)、舒张末期心肌质量(MMED)、平均心肌质量(MMAVG)。使用SPSS 20.0软件统计测量参数值的均值(■)和标准差(SD),应用独立样本检验男女两组的差异显著性,采用Pearson相关分析检验有关参数的相关系数,以P<0.05为差异显著。结果:30例均完成了右心室功能的心脏MR成像。右心室功能的心脏MRI测量正常值如下:EF=38.24±8.46(%),EDV=101.78±31.02(ml),ESV=66.14±21.16(ml),MMED=59.89±18.22(g),MMAVG=63.60±19.37(g),上述测量值在男女两组比较无显著性差异(F=0.028～3.764,P>0.05),SV在男性组为41.38±15.05(ml),女性组为29.06±8.38(ml)(F=5.832,P=0.023);CO在男性组为3.03±0.97(l/min),女性组为2.08±0.58(l/min)(F=4.270,P=0.048),SV和CO在男女两组间有显著性差异。通过Penrson相关检验,男性组SV与CO(r=0.918,P=0.000),SV与体重(r=0.420,P=0.105),CO与体重(r=0.353,P=0.179);女性组SV与CO(r=0.933,P=0.001),SV与体重(r=0.153,P=0.602),CO与体重(r=0.061,P=0.836)。结论:右心室功能MR成像的EF、EDV、ESV、MMED和MMAVG测量值在男女两组间无差异,而SV和CO测量中存在显著性差异,故应分别参照有关测量值进行右心室功能测评。
Objective: To study cardiac MRI evaluation of the right ventricular function. Methods: 30 cases of healthy volunteers(male=16 , female=14 , age range 19-38 years , mean age=27.21 years) were underwent the right ventricular short axis cine imaging on siemens 1.5T SomatonAera magnetic resonace system.By using Argus 4D VF ventricular function software, EF , EDV , ESV , SV , CO , MMED , MMAVG of the right ventricle were measured respectively . By using SPSS 20.0 software,the mean(X) and standard deviation( SD ) of mearment values mentioned above were abtained . The statistically significant differences were performed by independent samptes test , and the correlation between some measured values was evaluated by Pearson correlation analysis . P<0.05 was defined the signiffecant difference . Resalts: Cariac MRI of right ventricular function was obtained in 30 cases . Normal values of the right ventricular function were as following : EF=38.24±8.46(%), EDV=101.78±31.02(ml), ESV=66.14±22.16(ml), MMED=59.89±18.22(g), MMAVG=63.60±19.37(g), which values were no any difference for two gender groups (F=0.028~3.764, all P>0.05). There were significant differences on SV and CO for two gender groups. SV were 41.38±15.05(ml) and 29.06±8.38(ml) for male group and female group respectively (F=5.832, P=0.023), CO were 3.03±0.97(l/min) and 2.08±0.58(l/min) for male group and female group respectively (F=4.270, P=0.048).(r=0.918, p=0.000),(r=0.420, p=0.105) and (r=0.353, p=0.179) for SV with CO , SV with weight , CO with weight in male group , and (r=0.933, p=0.001),(r=0.153, p=0.602) and (r=0.061, p=0.836) for SV with CO , SV with weight , CO with weight in female group were showed by Pearson corretation analysis . Conclasion: There are no any difference in EF , EDV , ESV , MMED and MMAVG on cardiac MRI of the right ventricular function for two gender groups , but there are significant diffirences in SV and CO measurement , which will be useful for cardiac MRI evaluation of the right ventricular function.
