Free breathing 3D imaging of right ventricular structure and function using respiratory and cardiac self-gated cine MRI compare with traditional 2D SSFP cine MRI. The purpose of this study is to test the utility of 3D SSFP for RV quantification. 2D and 3D cine MRI were performed in random order on seven normal volunteers. RV chamber volumes were measured by manual planimetry at end-diastole and end systole and used for calculation of RV ejection fraction. These data demonstrate that free breathing 3D cine MRI can comprehensively assess RV structure and function. Future study is necessary to augment temporal resolution of 3D cine MRI and test performance for RV assessment in routine clinical practice.
