A Common Misunderstanding in Lung Ultrasound: the Comet Tail Artifact
1A&E, Khoo Teck Puat Hospital, Singapore
The comet tail artefact is probably one of the most commonly and loosely used term to describe vertical artefacts found in lung ultrasound. However, two distinct artefacts; the lung comets and the B-lines; which have different generation mechanism and clinical significance are commonly observed. This presentation explores the current understanding and use of these two artefacts in lung ultrasound diagnosis and how to avoid the pitfalls related to using the term comet tail artefact without distinction.
