Title: The Comparative Study of MRI,Echocardiography and MSCT in Assessment of Left Ventricular Myocardial Function
Abstract: Objective To assess the correlations between multislice computed tomography (MSCT) and echocardiography in assessment of left ventricular myocardial function, and to compare the results with magnetic resonance imaging (MRI). Materials and Methods End-diastolic-volume (EDV), end-systolic-volume (ESV), stroke-volume (SV), ejection-fraction (EF), and myocardial mass (MM) were calculated from 32 patients scheduled for MSCT angiography of the coronaries suspected of coronary artery disease (CAD).The results from MSCT and echocardiography were compared with MRI.Results There was no significant difference among the measurements for MSCT and MRI of the ventricular function parameters. A strong correlation between MSCT and MRI (r=0.78~0.92) was found for all parameters. There was also no significant difference among the measurements for echocardiography and MRI of the ventricular function parameters. Echocardiography and MRI had good correlation for EDV (r=0.63) and SV (r=0.69), and a low or moderate correlation for ESV (r=0.41), and EF (r=0.34) .However, EDV, ESV, SV, and MM were overestimated with MSCT compared to MRI, while EF was underestimated in MSCT. Echocardiography revealed overestimation of EF and an underestimation of EDV and ESV.Conclusion A strong correlation between MSCT and MRI is found for all parameters. ECG-gated MSCT angiography can evaluate the coronary tree, whereas the analysis of left ventricular parameters provides additional information of cardiac function without further radiation exposure or scan time. Moreover, the functional analysis with MSCT is more accurate than that with echocardiography.
