Collapse Navigator 3D SSFP Whole Heart Imaging

Purpose/ Objective

Volumetric imaging of the whole heart and the great vessels is very important for surgical planning and clinical decision making, particularly in complex congenital heart diseases. However, volumetric imaging is challenging due to presence of respiratory and cardiac motion. Gadolinium contrast injection is still a concern for patients with severe renal impairment and contrast allergy, as well as the need for intravenous cannulation. With use of a navigator 3D SSFP sequence, volumetric bright blood imaging can be achieved without the need for contrast injection. However, this sequence is still limited by the intrinsic limitations of SSFP sequences (e.g. presence of dephasing artifacts in regions with turbulence) and the need for additional scanning time due to dual gating. Volumetric imaging of the whole heart and the great vessels is very important for surgical planning and clinical decision making, particularly in complex congenital heart diseases. However, as the heart is beating and the diaphragms are moving, respiratory and ECG navigation must be performed to minimize motion artifacts. With use of a balanced SSFP sequence, bright blood imaging can be achieved without the need for contrast injection.
