To assess functional parameters using multidetector-row computed tomography (MDCT) and echocardiography and to compare the results with magnetic resonance imaging (MRI).
End-diastolic-volume (EDV), end-systolic-volume (ESV), stroke-volume (SV), ejection-fraction (EF), and myocardial mass (MM) were calculated based on CT data sets from 52 patients. Echocardiography was performed in 24 of the 52 patients. The results from MDCT and echocardiography were compared with MRI.
A strong correlation between MDCT and MRI (r=0.66-0.90) was found for all parameters. Echocardiography revealed a low or moderate correlation (0.05-0.59). Compared to MRI the average differences with MDCT were for EDV 15.1 ml, ESV 10.6 ml, SV 4.5 ml, EF 1.8%, and MM 8.2 g, for EDV determined by echocardiography 36.2 ml, ESV 6.8 ml, and EF 13.9%. Bland-Altman analysis revealed acceptable limits of agreement between MRI and MDCT.
MDCT enables reliable quantification of left ventricular function. Echocardiography was found to have only a moderate agreement of functional parameters with MRI.
使用多排螺旋计算机断层扫描(MDCT)和超声心动图评估功能参数,并将结果与磁共振成像(MRI)进行比较。
基于52例患者的CT数据集计算舒张末期容积(EDV)、收缩末期容积(ESV)、每搏输出量(SV)、射血分数(EF)和心肌质量(MM)。52例患者中的24例进行了超声心动图检查。将MDCT和超声心动图的结果与MRI进行比较。
发现所有参数在MDCT和MRI之间均具有强相关性(r = 0.66 - 0.90)。超声心动图显示相关性较低或中等(0.05 - 0.59)。与MRI相比,MDCT的平均差异为:EDV 15.1 ml、ESV 10.6 ml、SV 4.5 ml、EF 1.8%、MM 8.2 g;超声心动图测定的EDV为36.2 ml、ESV为6.8 ml、EF为13.9%。Bland-Altman分析显示MRI和MDCT之间的一致性限度可接受。
MDCT能够可靠地定量左心室功能。发现超声心动图在功能参数方面与MRI仅具有中等程度的一致性。
