Objective: It is important to measure left ventricular function (LVF) accurately in the diagnosis and follow-up of cardiovascular diseases. Different imaging algorithms and mathematical calculations have been developed for the evaluation of LVF in cardiac magnetic resonance imaging (MRI), and numerous studies are still being carried on this. In our study, LVF was calculated by two different measurement methods in MRI and were compared with transthoracic echocardiography (TTE) to assess the correlation and the consistency of these with TTE.

Materials and Methods: In this study, 31 patients with left ventricular dysfunction due to different etiologies were evaluated with simultaneous TTE and MRI. In the Cine MR images, LVF parameters of ejection fraction, end-diastolic volume, end-systolic volume, and myocardial mass were measured using short axis images (short axis method) and short axis plus four chamber and two chamber images (combined method). The results were compared with the results from TTE.

Results: We found that the combined and the short axis–based calculations of ejection fraction, end-diastolic volume, end-systolic volume, and myocardial mass in cardiac MRI showed correlation and consistency with those calculated via echocardiography. We also determined that the short axis–based calculations in cardiac MRI showed better correlation with the echocardiography compared with the combined method.

Conclusion: Because our results revealed that the cardiac MRI results obtained from the short axis method better correlate with the TTE, we recommend using short axis–based measurements in the evaluation left ventricular dysfunction.
