Steady-state free precession (SSFP) is the sequence of choice for evaluating left ventricular (LV) function, but conventional 2-dimensional (2D) techniques require multiple breath-holds. We combined 3-dimensional (3D) SSFP with sensitivity encoding (SENSE) to achieve a single breath-hold acquisition. We imaged 23 individuals with both the 2D and 3D sequences and compared these two methods for quantifying LV function. 3D SSFP imaging with SENSE reduced the acquisition time to a single breath-hold and provided LV function assessment comparable to that obtained with conventional 2D SSFP imaging.
