53 Volume-Interpolated Breath-Hold Examination (VIBE)

The outer lines of k space contain information about the details within the image, the high spatial frequencies. For a heterogeneous object, there is some signal in this portion of k space, although it is very small. Omitting data collection from this part of k space causes truncation artifacts (see Case 104). Filling these data lines with zero values (as illustrated in Fig. 53.1B) will greatly improve the image appearance. Figure 53.1A illustrates the situation in which all k-space lines are acquired in a 3D scan. In Fig. 53.1B
