evaluation and comparison of left ventricular function by cardiac mri vs 2d transthoracic echocardiography

Abstract

Ejection fraction is the best method to assess the function of the left newlineventricle. It can be done by using 2D Echocardiography and Cardiac MRI. newlineECHO is most widely used because it is very cost effective and hence newlineavailable widely. The cost of an MRI machine is very high and hence newlineCardiac MRI is not easily available. ECHO is used dependent and there is newlineno inter or intra observer variability in cardiac MRI. newlineTo evaluate and compare the accuracy of calculation of ejection fraction newlinebetween 2D Echocardiography and Cardiac MRI(CMR). newlineThe study was done with 85 patients across varied age group and both newlinesexes. All the patients underwent 2D ECHO and CMR. CMR was done in newlineshort axis and long axis views. Results were calculated using appropriate newlinemethods it was concluded that CMR is superior to 2D ECHO in accurately newlinecalculating the ejection fraction. The short axis method correlates well with newlinethe values obtained from2D ECHO than the results obtained from long axis newlineviews. Obtaining accurate values help in staging of the heart failure patients newlinewhich in turn help in the appropriate patient management newline
