Abstract

AbstractBalanced steady‐state free precession (SSFP) sequences are useful in cardiac imaging because they achieve high signal efficiency and excellent blood–myocardium contrast. Spiral imaging enables the efficient acquisition of cardiac images with reduced flow and motion artifacts. Balanced SSFP has been combined with spiral imaging for real‐time interactive cardiac MRI. New features of this method to enable scanning in a clinical setting include short, first‐moment nulled spiral trajectories and interactive control over the spatial location of banding artifacts (SSFP‐specific signal variations). The feasibility of spiral balanced SSFP cardiac imaging at 1.5 T is demonstrated. In observations from over 40 volunteer and patient studies, spiral balanced SSFP imaging shows significantly improved contrast compared to spiral gradient‐spoiled imaging, producing better visualization of cardiac function, improved localization, and reduced flow artifacts from blood.
