A description and explanation of an unexpected echographic appearance in a patient who had sustained an abdominal shotgun wound is presented. In the B-scans, a trail of dense continuous echoes, simulating a comet tail, is seen distal to each lead pellet. This comet tail appearance is shown to be a type of reverberation artifact.

The sign has been originally described on chest radiographs. It is formed by distorted blood vessel(s) and a focal area of atelectatic lung adjacent to pleural thickening. The vessel(s) are seen as curvilinear soft tissue density or densities, extending from the medial margin of the atelectatic lung to the pulmonary hilum. When the vessels are multiple

Vaccinia virus moves around infected cells propelled by comet-like actin tails. Newsome et al. (see the Perspective by Hall) have uncovered an outside-in signaling mechanism, induced by extracellular vaccinia virus particles, that is ultimately responsible for stimulating actin-based motility of vaccinia virus by ...

Color Comet-Tail Artifact: Clinical Applications
American Journal of Roentgenology, 2009This article explores the circumstances under which the color comet-tail artifact occurs and illustrates the clinical value of the artifact.Subtle abnormalities on gray-scale sonograms often are better appreciated and understood when the color comet-tail artifact is present.

Neutral sodium tails in comets
Advances in Space Research, 2002Abstract In the last few years, after a new type of tail composed only of neutral sodium atoms had been discovered in Comet Hale-Bopp, much attention has been given to the release and distribution of sodium in comets. It was not the first time that a sodium tail had been observed in a comet, but the amount of data collected from Comet Hale-Bopp in ...

Plasma Tail and Dust Tail of Comets
1994Generally, a comet has two tails; the blue plasma tail and the red dust tail (or Type 1 (ion) tail and Type 2 (dust) tail). The plasma tail is caused by an interaction between the solar wind and the cometary plasma, while the dust tail is by the solar radiation pressure to the cometary dust. The first purpose of the present paper is to review our works
