2022年8月23日 · Comet tail artefact is a short path reverberation artefact that weakens with each reverberation, resulting in a vertical echogenic artefact that rapidly fades as it continues in to …

2018年8月30日 · The comet tail artefact is probably one of the most commonly and imprecisely used to describe vertical artefacts found in lung ultrasound. Two distinct artefacts are …

(B) Comet-tail artifacts . These are a subtype of reverberation artifacts arising from highly reflective, closely apposed interfaces like calcium, cholesterol crystals, and metal, which …

Lung ultrasound diagnosis depends on the interpretation of changes or loss in the natural artifacts produce by lung air. Several vertical linear lung artifacts have been described, of which two …

2018年6月7日 · This review explores the current understanding and use of these two artefacts in lung ultrasound and suggests how to avoid the pitfalls related to confusing comet tail artefacts …

2013年11月6日 · Comet-tails or “B-lines” are defined as hyperechoic reflections which originate only from and travel roughly perpendicular to the pleural line of the lung. They have a narrow …

The comet-tail artifact was described as a reverberation effect, i.e., multiple reflections of an acoustic wave between two opposite internal walls of a strong reflector. The ring-down artifact …

The presence of B lines, which were previously called comet-tail artifacts, generated from the thickened interlobular septa at the lung wall interface was assessed. These were defined as …

The comet tail artefact is probably one of the most commonly and imprecisely used to describe vertical artefacts found in lung ultrasound. Two distinct artefacts are commonly observed: the...

2023年10月28日 · The comet tail artifact is a grey scale ultrasound finding seen when small calcific / crystalline / highly reflective objects are interrogated and is believed to be a special …
