چکیده

PURPOSE The purpose of this study was to compare long axis and short axis methods in cardiac magnetic resonance imaging (MRI), and echocardiography for the evaluation of left ventricular function and mass. MATERIALS AND METHODS The study included 15 patients with a history of myocardial infarction and 5 patients with normal ventricular function who were examined with cardiac MRI and echocardiography. Left ventricular function and mass analyses calculated with Simpson's method from short axis images were compared to the results of horizontal long axis, vertical long axis, and combined axes methods. In addition, results obtained from echocardiography were compared to the short axis method in cardiac MRI. RESULTS In the patient group, there was no significant difference between ejection fraction calculated by modified Simpson's analysis in echocardiography and short axis imaging in cardiac MRI. In cardiac MRI, there was significant difference between ejection fractions assessed from both horizontal and vertical long axis images, and those assessed from short axis images. There was no significant difference in both patient and control groups between end-diastolic volume determined from short axis and end-diastolic volume determined by horizontal long axis, vertical long axis, and combined long axes. Significant difference between the patient and control groups was observed in end-diastolic volume calculated by modified Simpson's echocardiographic method. CONCLUSION The present study demonstrated that there were no significant advantages of simplified MRI techniques over modified Simpson's method echocardiography. Therefore, patients who cannot be evaluated by echocardiography optimally should be evaluated by short axis cine MRI sequence.

Assessment of left ventricular torsion in long axis view in patients with chronic stenosis of coronary arteries

Background: Left ventricular torsion is one of the most important biomechanical parameters of heart that routinely is measured in short axis view.  A review of the literature has indicated that assessment of left ventricular torsion in short axis view has some limitations. In the present study, we evaluated whether torsion angle assessment in long axis view can be used as a diagnostic biomechan...

Comparison of Fetal Echocardiography for Fetal Cardiac Structure in Women with Gestational Diabetes Mellitus and Normal Pregnancies

BackgroundIncreased metabolic rate of hyperglycemia in gestational diabetes causes macrosomia, which can also affect the fetal heart. The thickness of the walls of the heart and its function in women with gestational diabetes mellitus (GDM) can change over time before treatment. We aimed to evaluate fetal cardiac structure in terms of ventricular wall thickness and its function in women w...

Echocardiographic Assessment of Left Ventricle Torsion by Tissue Doppler and Velocity Vector Imaging

Introduction Left ventricular (LV) twist is believed to store potential energy and plays an important role in generating diastolic suction. Recent advances in echocardiography techniques have allowed quantification of LV twist. The aim of the present study was to compare LV twist and torsion in healthy human subjects determined by velocity vector imaging (VVI) and tissue Doppler imaging (TDI) a...

Diastolic left ventricular functional indices: Comparison between gated myocardial perfusion SPECT and echocardiography

Introduction: Many patients have only diastolic dysfunction without any abnormality in systolic function. We compared cardiac diastolic parameters obtained by gated myocardial perfusion SPECT (Gated SPECT) with those evaluated by echocardiography. Methods: Forty-nine patients (aged 37-85 years, 19 males and 30 women) underwent Gated SPECT and echocardiogr...
