Fetal tibia\/fibula and radius\/ulna pairs were assessed for completeness of imaging. A further 20 fetuses (gestational age 20\u201326 weeks) were scanned in both axial and sagittal planes and the results compared to verify clear visualization of both bones.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Shadowing from adjacent structures produced an apparent limb defect in 55% of the first 20 fetuses imaged only sagittally (18% of limb pairs). Acquiring data from more than one orientation avoided this artifact.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The 3D US is subject to the same artifacts as two\u2010dimensional (2D US) in terms of acoustic shadowing, although their presentation may be different. Awareness of this fact is essential for correct interpretation of 3D US studies. Three\u2010dimensional scanning protocols should be modified to ensure that fetal structures are adequately visualized by acquiring volume data in more than one acquisition orientation.
