Key result
Real-time trueFISP cine MR imaging permitted assessment of left ventricular function in a single breath-hold, although with lower temporal and spatial resolutions than segmented trueFISP.
Observational
May enable faster left ventricular assessment in breath-hold-limited patients; leaves open whether lower resolution compromises diagnostic accuracy.
OBJECTIVE: The aim of our study was to evaluate whether a recently developed real-time steady-state free precession (trueFISP) cine sequence could be used to assess left ventricular function in a single breath-hold. CONCLUSION: Using real-time trueFISP permits one to assess left ventricular function in a single breath-hold. The dramatic reduction in data acquisition time does require some compromises. The temporal and spatial resolutions of images obtained with real-time trueFISP were considerably lower than those achieved with segmented trueFISP. Further reduction of the TR or the use of sensitivity encoding could improve temporal resolution and eliminate other limitations of real-time trueFISP.

Barkhausen et al. (2002) conducted an observational in Left ventricular function assessment. Real-time steady-state free precession (trueFISP) cine sequence vs. Segmented trueFISP was evaluated on Assessment of left ventricular function. Real-time trueFISP cine MR imaging permitted assessment of left ventricular function in a single breath-hold, although with lower temporal and spatial resolutions than segmented trueFISP.
