The color comet-tail artifact is an ultrasonographic sign seen in a number of situations when color Doppler scanning is performed.

Typically the artifact, which resembles the grey-scale comet-tail artifact, is seen in a situation when a small highly reflective (usually calcific) object is interrogated with color Doppler. Twinkling artifact occurs and immediately deep to the object a tail of linear aliased band of color extends away from the probe.

The following are situations in which this sign may be present and helpful:
