Fig. 4D —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, {alpha} =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 [Tacq] = 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 right coronary artery (RCA) in 29-year-old healthy man acquired at trigger delay of 614 milliseconds obtained by visual assessment method (C) and at trigger delay of 561 milliseconds obtained by FREEZE (D). Length of visible vessel (arrows) is increased in image acquired with FREEZE.
