Description: With ultrasound, not everything is as it appears to be. Sometimes, structures appear that do not exist, sometimes structures do not appear that do exist, and sometimes structures appear differently than they really are. When any of these situations occur, artifacts exist in the image. In this module, you will learn what an artifact is as well as the most common artifacts, their causes, and how you recognize these artifacts in the image. Most importantly, by understanding the mechanisms that cause the artifacts, you will recognize the existence of artifacts when they occur and understand what the artifact tells you about the structures in the body that are causing the artifact.
