摘要：

Acoustic shadowing may be seen distal to the margins of rounded structures having different acoustic velocities from the surrounding tissue. Refractive and reflective mechanisms for such shadowing are reviewed and in vitro demonstrations of such shadowing are presented. Clinical examples of refractive and reflective shadows are given, and their importance is discussed.
