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:
- small renal or ureteric calculi
- small common bile duct stones
- adenomyomatosis of the gallbladder
- pancreatic calcifications of chronic pancreatitis
- testicular microlithiasis (sometimes)
- identification of foreign bodies
- surgical clips
- catheter tips
- debris/glass/metal
