Title: Evaluation of left ventricular function by using 64-slice spiral CT
Abstract: Objective To investigate the clinical value of 64-slice spiral CT(64SCT) in assessing left ventricular function.Methods A total of 35 patients were suspected or confirmed with coronary artery disease underwent ECG-gated enhanced 64SCT,left ventriculography(LVG) and echocardiography(Echo).The data sets of 64SCT,LVG and Echo were reconstructed at both end-diastole and end-systole to measure left ventricular end-diastolic volume(EDV),end-systolic volume(ESV),ejective fraction(EF).Three inspection methods lasted no more than a week.Results The parameters of left ventricular function(EDV,ESV,EF) obtained with 64SCT were significantly correlated with the Echo(r=0.85-0.90,P0.01).EDV and ESV were significantly overestimated by 64SCT compared with Echo(P0.05),whereas EF was not significantly different,consistency could be clinical acceptance.Evaluation of EDV,ESV,EF by linear regression analysis showed a good correlation between 64SCT and LVG,EF were significantly underestimated by 64SCT compared with LVG(P0.05).Conclusion EDV,ESV and EF determined by 64SCT have excellent correlation,good reproducibility and an fair agreement with LVG and Echo.64SCT is an accurate and reliable method in quantitative evaluation of left ventricular function.
