Patients with congenital heart disease (CHD) often have complicated ventricular motion and configuration. Myocardial feature tracking (MFT) MRI can quantitatively analyze 2-dimensional myocardial motion. Although three-dimensional (3D) MFT is required for the patients with CHD, standard cine MRI is limited the setting of thin slice thickness attributed to increasing scan time. In this study, we analyzed bi-ventricular function with 3D MFT using only standard cine MRI datasets reconstructed by moving gradients based image interpolation technique. As the result, 3D MFT is useful to evaluate bi-ventricular function for patients with CHD, and can be easily applied to routine clinical MR examination.
