Why the study?
Does free breathing respiratory triggered SSFP imaging provide comparable image quality and LV function metrics to breath-hold SSFP imaging in adults undergoing CMR?
Does free breathing respiratory triggered SSFP imaging provide comparable image quality and LV function metrics to breath-hold SSFP imaging in adults undergoing CMR?
Free breathing respiratory triggered SSFP provides comparable LV function evaluation and image quality to standard breath-hold SSFP, offering a robust alternative for patients unable to hold their breath.

Free-breathing RT-SSFP yields comparable LV metrics and quality; supports use in breath-hold intolerant patients but leaves open prospective validation.
Background The cine steady-state free-precession (SSFP) is the standard sequence for left ventricular (LV) function evaluation. However, SSFP mandates uninterrupted RF excitations to maintain steady-state (SS) during suspended respiration. In patients who cannot perform breath-holds (BH), a respiratory triggered (RT) free breathing (FB) retrospectively cardiac gated cine SSFP sequence that drives the magnetization to SS before commencing cine acquisition may be an alternative [1]. In this work, we validate the RT FB SSFP sequence by comparing it to the BH SSFP sequence for LV function evaluation.
