Fig. 4E —Volume-targeted navigator-gated and navigator-corrected double oblique 3D segmented k-space gradient-echo images obtained in three subjects (3 T, TR/TE = 4.3/1.47, =20°, resolution=0.7x1x3 mm, field of view = 360 x 270 mm, 512 x 268 matrix, 16 radiofrequency excitations per R-R interval, acquisition time window [T_acq] = 69 milliseconds, bandwidth = 362 Hz/pixel, scan duration = 145-259 seconds depending on navigator efficiency and heart rate, 10 slices [acquired], 20 slices [reconstructed using zero filling], fat saturation, adiabatic T2 prepulse [TE = 50 milliseconds]). Oblique sagittal views of RCA in 33-year-old healthy man acquired at trigger delay of 674 milliseconds obtained by visual assessment method (E) and at trigger delay of 193 milliseconds obtained by FREEZE (F).
