Example of motion artifacts in the wall of the longitudinal descending aorta in a STIC volume dataset. The left image shows a straight wall, consistent with absence of fetal breathing during the STIC acquisition. However, the right image shows a “wavy lasagna wall,” indicating regular fetal breathing during the STIC acquisition. Thus, this volume is not appropriate and should be discarded.
