Breath-hold ECG-segmented and free-breathing real-time tagging imaging. Steady-state free-precession tagging images were collected in patients (a–c) and a healthy subject (d) at 3 T. Tag lines with 8 mm thickness were oriented 90° perpendicular to the phase encoding, which resulted in horizontal and vertical lines. Three slices at basal, mid, and apical levels were acquired. Imaging parameters for both ECG-segmented and real-time acquisitions were: matrix size = 176 × 176, acquired spatial resolution = 4.0 × 2.0 mm2, reconstructed spatial resolution = 2.0 × 2.0 mm2, slice thickness = 8 mm, slice distance factor = 150%, echo and repetition time = 1.1/2.62 ms, temporal resolution = 28.8 ms and flip angle = 30°. Images are shown at end-systole. ECG electrocardiogram
