Abstract
Aims: To study the correlation of Cardiac function/ejection fraction derived from 128 slice MDCT (multi detector computed tomography) results with those of functional data from 2D/M-mode echocardiography.
Study Design: Retrospective, comparative study with empirical data.
Place and Duration of Study: Department of Radiology at K. Govindaswamy Naidu Medical Trust hospital, Coimbatore, between May 2013 and October 2013.
Methodology: For this study, 44 patients (M: F = 35: 9; mean age = 49 years) were randomly chosen who had come between May 2013 and October 2013. All the patients were referred to our department from cardiology as well as non-cardiology OPD’s for coronary CT angiography. Ejection fraction data was obtained using two methods; M-mode echocardiography and 128-slice MDCT using retrospective ECG gated coronary angiographic study.
Results: The mean of LVEF (left ventricle ejection fraction) by echo is 64.73 with standard deviation of +/- 5.48 and the mean of LVEF by cardiac CT is 65.18 with standard deviation of +/- 8.70 with P- value of 0.770 (P value ranges from 0-1) which shows good correlation. The evaluation of LVEF by linear regression analysis show good correlation between LVEF by echo and MDCT. (r= 0.486). [r value ranges between -1 and +1].
Conclusion: This study shows the cardiac function evaluation using 128 slice MDCT is as good as the 2D- echocardiography thus the results are interchangeable between the modalities.
